Yes the Cock and Bull band did record some Irwin tunes. I should really get round to producing a list of people who've recorded tunes from his repertoire. Off the top of my head, Hodgett's Barnstormers, Crookfinger Jack, Cock and Bull Band, Eliza Carthy, ther Boat Band, the Old Friends Ceilidh Band, Altarnative, the Lakeland Fiddlers. There's probably more.
