There is more than one artist with this name, an Irish folk band as well as a French rock band: 1. Irish jigs abound, as well as some subtle influences from modern rock and jazz. They have been hailed as the greatest folk band in the world today. Formed in 1996, the band's original lineup consisted of Seamus Egan (flute, tenor banjo, mandolin, tin whistle/low whistle, guitar, bodhrán), Winifred Horan (fiddle), John Doyle (guitar), John Williams (accordian), and Karan Casey (lead vocals). Over the years, only Egan and Horan have stayed with the band.
