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 Limerick native 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.
