I love this song, and here is another short recording of it, Seamus Ennis in 1951 recorded by Alan Lomax. The tune Seamus uses is similiar to Pretty Molly Brallaghan or the jig Maid in the Meadow (which Seamus called the Stone in the Field) or the reel the Green Fields of America. It's also on Topics Voice of the People Vol 14, with another melody - don't know which one is sung usually.
