On April 30th 1994 something happened during the interval of the Eurovision Song Contest that was to lead to the creation of one of the most successful stage shows of all time and introduce the wider world to Irish dance and music.
As votes were being counted around Europe, in Dublin in the Point Theatre (now the O2), RIVERDANCE burst onto the stage and took the audience by complete surprise.
From the haunting vocals of Anúna, the graceful elegance of Jean Butler, the explosive arrival of Michael Flatley and culminating in a long line of Irish dancers beating the stage in perfect heart-stopping harmony - a whole new genre of entertainment was born and 20 years and 25 million audience members later - Riverdance still astonishes globally.
