Planxty were an Irish folk music band formed in January 1972, consisting initially of Christy Moore, Andy Irvine, Dónal Lunny, and Liam O'Flynn. They transformed and popularized Irish folk music, touring and recording to great acclaim.
Subsequently, Johnny Moynihan, Paul Brady, Matt Molloy, Bill Whelan, Nollaig Casey and briefly, Noel Hill and Tony Linnane were also temporary members.
Planxty broke up twice, first in December 1975 and again in April 1983. The original quartet reunited in October 2003 and their final performance was on 31 January 2005.
