They both seemed to be so excited to perform with each other. Total respect and admiration for one another.

67 years old and able to have his shirt open. Nice work Billy!

Love her or hate her Miley can perform. Versatile. Talent. And how in the F*** is Billy sounding this good at his age? Respect.

They compliment each other SO well it’s insane

This was honestly the best use of my last 2% battery

Originally, I dismissed her as just another pop star but I have to say, she's an extremely versatile artist with a fantastic vocal.

She should definitely sing rock! Her voice really rocks!

The kid has an amazing range. There's no denying that she's good at what she does. This is an incredible performance

Phenomenal duet. Billy sounds the same as when this was first released and Miley’s vocals are out of this world. Is there any genre she can’t sing. Mind blown 🤯

If Miley releases a rock album I am definitely buying it. I think she has shocked many people and gained a lot of new fans with her series of rock covers and collaborations. Her voice is amazing

Billy sounds outstanding. And the chemistry with Miley is also excellent. Loved this !

Billy is another rock legend,he's aged very well and still sounds and looks amazing! And Miley is a heck of a performer too.

Billy was overwhelmed with this. He truly delighted in the duet. LOVE both of them. Can we agree Billy still has that amazing stance when he sings. It is his signature.

Miley's Billy Idol fangirl outfit is everything.

Been to a million concerts. Along with Bon Jovi, Billy's live performance is every dam bit as good as it is on the radio. Couldn't possibly recommend any solo artist higher than Billy Idol.

I’ve always been indifferent about Miley, but my God she nailed this and gave me goosebumps!

Can we all agree that Billy Idol has aged amazingly. It's unbelievable

Their chemistry on stage is mesmerizing ,Miley is a chameleon she can sing everything.

Billy is such a beautiful human being, I'm glad a whole new generation get to see and hear how awesome he really is.

The way she went into the chorus the first time gave me goosebumps omg her voicee 🤯🤯

Time for Miley to get recognized as the generational talent that she is. I saw her live last summer and she is up there with the best live shows I have seen, period.

Billy Idol still has the same abs as he did in the 80s

This is the song of my teenage youth...Yes I'm a Generation X 🤘😎✊

WOW. HE SOUNDS AMAZING FOR HIS AGE and looks great!! fantastic Billy. Miley’s voice is so powerful. This gave me goose bumps.

Can we just talk how hot Billy Idol is??? Dude is 64. And he sounds great! Miley did justice as usual!

Miley, thank you for reviving Rock 'N Roll!!!! From the 60's to the 21st century, you are doing Rock music PROUD!!!

Sick performance! And the way they match perfectly has my mind blown.Gave me chills. This genre fits miley more than pop i just wish she dedicated more of her time to this and switched her pop music career into folk country-rock music. Definitely nailed this.

Most of those girl in that concert have never heard Billy Idol.. Gotta respect Miley for bringing back a legendary singer like him.

He truly looked like he was having an amazing time on stage with her. Awesome song and great duet! Loved it!

Almost 40 years and this song are still rocking.

Legendary. Give it another 5-10 years. Miley is going to be branching beyond pop and become a bonafide ROCK star!!!

This is the coolest thing that has happened to rock music lately! They were both amazing!

Billy still sounds and looks incredible

Billy is 66 years old and still sounds and looks awesome! He's got a grandbaby, can you imagine how kick ass it would be to have Billy fckn Idol as your grandfather???

Her voice is 10000% rock now!

This is so great! Im 50 and a big fan of Billy first and Miley is a New BIG Star. Love to see this!!!!

Respect to Miley for introducing this legend to the youth.

Easily one of the coolest duets I've ever seen. Wow!!! Billy still has it, and Miley slayed.

She is amazing at all of these classic rock songs. I can't get enough of her voice in that capacity! ❤😍

Fan or not....this was epic! Hat off to both of you, Billy and Miley! The 80's rocked! ✊🏻 Now, where can I find a time machine!

The set is insane. The partnership is insane. The guitarists are insane. Billy and Miley are a match made in heaven. Quite possibly the best feel good duet ever....just insanely brilliant.

Can we just take a moment to acknowledge 2 things? : 1. Billy looks and sounds absolutely amazing!! 2. The way Billy was looking at Miley with such awe and admiration!

Here I am coming back to this iconic performance for the millionth time. It just never gets old. Legends ❤️‍🔥

That was absolutely LEGENDARY 😮😮😮😮

Damn I swear Billy's voice ain't changed at all he still sounds just as fabulous as he did back then

He's a legend, great singer, performer and artist. Props to Miley Cyrus, the girl can sing the arse off anything. Great combination of generations

Absolutely fantastic! What a combination of their voices. Love both artists, and to hear them sing together on this…well friggin’ awesome!😉👏🏼👏🏼💗

Talk about synergy, one of the best performances of a duet version I've seen done in a long time! Absolutely incredible. AND??? FOR ONCE THE FEATURED ARTIST'S (in this Case, Original Singer: Billy Idol), MIC WASN'T TOO LOW, WEREN'T DROWNING EACH OTHER OUT/COMPETING!!! & he more than still got it. Fricken LEGEND!! What a f'ing honor to perform with this god of a legendary singer, man. Holy heck! ANd! She absolutely did incredible singing it but particularly WITH him!!! This was fricken BADASS!!! I am so greatful to see this!

I can’t believe he sounds EXACTLY like the album after all of these years. I don’t think I can honestly say that about any other artist. That’s insane!!! And like someone commented, her voice sounded a lot better than anything I’ve heard from her. She kicked butt complementing the song.

Miley rules. And Billy Idol is still performing with his top off! 🤘

Billy's voice was incredible live, at any age.

OMG!!!! Just found this performance...play it f'ing LOUD!!!!! Rebel Yell is my favorite of the Billy songs and you can't get better than Stevie Stevens. God, I miss the 80's.

Every second of this performance is gold. What chemistry! Billy looks fantastic and has aged with dignity and grace. I thought I had seen it all, but now all my fellow 50 year-old former 80s punk friends are totally into and respect Miley Cyrus!!

Gosh his voice sure held up over the years. Great voice

Wow, iconic song. I cant imagine how thrilled she must have been to sing with Billy

61 years old never looked better, what an inspiration

Now everytime i think of billy idol, i think of AHS 1984

Who’s here after Night Crawling? 🔥

what a combination of two fantastic artists.

Billy Idol Legend!! Imagine Billy and Miley being a duo back in the 80’s ===❤❤❤🔥🔥🔥

Props to Steve Stevens -- his guitar playing is amazing!

Her ability to sing anything can't be understated. Her classic rock covers are fearless and perfect.

Billy Idol's band just rocks!

I honestly can’t see why stadium 80s rock couldn’t make a revival again. These kids look like they are loving it.

I am surprised and in awe of Miley and how she can sing just about any genre and alternate with Metallica, Billy Idol or even Dolly Parton..this girl has some serious pipes!!!

god i love seeing miley doing rock, her voice was hand crafted for it.. its insane also they work SO well together!! their chemistry is awesome they have the same energy

I don’t think it would be easy to keep up with Billy Idol and she did it effortlessly ❤

Billy Idol like one of the best front men to ever do this thing. Definitely one of a kind.

She goes to lunch with Billy frkn Idol.... casually.... she has the best life

Steve Stevens is probably one of the most underrated guitarists.

It is an explosion! Billy and Miley where is your tour together?

Love it , i'm an old fart stuck listening to my ERA of music which is Punk & 80's & the last CD I bought was The Black Keys El Camino until I heard all the singles from Plastic Hearts on the Radio & had to buy that album

I’m a middle-aged woman, and I still go weak at the knees when I hear Billy Idol’s voice.❤️‍🔥

Since I’ve found this I’ve listened to it at least 50 times. Love it. Look how happy Billy is.

We need rock Miley!

She is a real rock star, pure talent, and Billy is fucking great.

Glad to see her getting to her roots! That voice was crafted for this genre

I grew up listening to Billy Idol and my daughter loves Miley Cyrus so not only was this an awesome song it was a great bonding experience for me and my daughter

everything miley in... come back or hit again..... she is boosting every one .... cuz she is the only diva in this 2020s

A time machine brought 2 legends from different generations together to shatter airwaves. huge respect

Steve Stevens (Guitarist) a talent in his own right.

Holy shit, Billy Idol looks like he walked right outta the 80s. Dude..does..not..age!!!!

Wow, why am i only just seeing this, hes 69 now, 67 when this was filmed, love him, miley was so good, they suit each other so well...he looks fabulous!! 💕💕💕

A true rock legend performing with a future legend! Great performance!!

It doesn’t get any better than this. Billy Idol is in top form, adding Miley Cyrus kicks a great song up about three notches, and the guitarist, Steve Stevens, is jaw droppingly great. That’s a whole lot of badass rock and roll on one stage at the same time.

Billy Idol is keeping up with a lady half his age! Still looks and sounds amazing. Miley also rocked this cover!

I was left in tears of happiness for Billy ----he should make a comeback!!!!

My Idol from my youth and the greath Miley Cyrus...great to listen to!🎉

Their voices together are so amazing I didn’t know that I needed this in my life

Actually jaw dropped when Billy started singing. I didn’t except him to sound so amazing still.

A special mention to the guitarist. To his magic touch that made this song so great . Forever.

This was absolutely amazing!! Billy looks and sounds fantastic and Miley’s voice was made for rock music!! Amazing amazing amazing performance!!!!

Freaking amazing billy idol is a legend Miley was fabulous I love everything about this wow 🔥🔥🔥🔥❤️❤️❤️

This has become one of my most favorite videos, those two rock!

Billy Idol's age: Undefined Billy Idol's birthplace: Transilvanya's general hospital. Miley Cyrus can sing whatever she wants, what an amazing voice!!!

Damn Billy idol sounds and looks amazing! In his 60's and still sounds and looks the same!

Billy idol kicks ass he will never age

WOW! Billy's voice still AMAZING. He's a legend.

Holy crap! Billy can still belt it out exactly how he did back in the day!
