Riverdance is a theatrical show consisting mainly of traditional Irish music and dance. Featuring Irish dancing champions Jean Butler and Michael Flatley, and with a score composed by Bill Whelan, it originated as an interval performance act during the 1994 Eurovision Song Contest. Shortly afterwards, husband and wife production team John McColgan and Moya Doherty expanded it into a stage show, which opened in Dublin on 9 February 1995. Since then, the show has visited over 450 venues worldwide and been seen by over 25 million people, making it one of the most successful dance productions in the world.
Riverdance is rooted in a three-part suite of baroque-influenced traditional music called Timedance composed, recorded and performed for the 1981 Eurovision Song Contest, which was hosted by Ireland. At the time, Bill Whelan and Dónal Lunny composed the music, augmenting the Irish folk band Planxty with a rock rhythm section of electric bass and drums and a four-piece horn section. The piece was performed, with accompanying ballet dancers, during the interval of the contest, and later released as a Planxty single. Whelan had also produced EastWind, a 1992 album by Planxty member Andy Irvine with Davy Spillane, which fused Irish and Balkan folk music and influenced the genesis of Riverdance. Thirteen years later, Bill Whelan was invited to do the intermission piece for another Eurovision Song Contest in Dublin, and composed Riverdance. In a book about Planxty (The Humours of Planxty, by Leagues O'Toole), Whelan says, "It was no mistake of mine to call it Riverdance because it connected absolutely to Timedance".
Riverdance was first performed during the seven-minute interval of the 1994 Eurovision Song Contest at the Point Theatre in Dublin on 30 April 1994. The performance earned a standing ovation from the packed theatre of 3,000 people. Due to the act's success, Riverdance was invited to perform at the prestigious Royal Variety Performance at Dominion Theatre, London in the presence of Prince Charles on 28 November 1994. The act was introduced on stage by Sir Terry Wogan. Both performances featured American Irish dancing champions Jean Butler and Michael Flatley, the RTÉ Concert Orchestra and the choral ensemble Anúna with a score written by Bill Whelan.
