Thread title pretty much says it - this evening Friday 19th on BBC4 TV at 9:00 until 10:30. Radio Times sez: "The revival of Irish folk music, which 60 years ago was virtually unheard outside Ireland [excuse me?????], with contributions from the likes of Christy Moore, Paddy Moloney, Shane MacGowan and Liam Clancy." According to the heading it's meant to be a new programme. (If that doesn't float yer boat, you can always switch over to National Geographic and watch the history of the toilet...)
