Moya Brennan is touring the US at the moment, with her "An Irish Christmas" tour. She's accompanied on stage by Cormac De Barra, Aisling Jarvis, Fergal Murray (keys) and Pat Mangan (fiddle). In this video you'll see the band performing in Colebrook NH and Moya being interviewed. The US tour continues until 14th December.
Update: Look at Concert Blogger for a great review of the Sellersville concert, including pics and setlist.
