Val, I think it was "The Irish in America" there are a couple of similar sounding shows. they usually air it around St. Patricks Day so if you think of it next year check to see if it's on. It has Mary Black, Luka Bloom, U2, The Everly Bros, John Prine, the Clancy Bros......hell too many to list here but be assured it is defineatly worth watching. good luck
