I'd almost forgotten this song, but there used to be a Scots singer who was a regular at the Bournemouth and Poole Folk Song Club in the mid sixties and he half taught me this one. He also used to sing MacColl's 'Big Hewer.' I think his name was Gordon McCulloch but I could be wronng. Given that Hamish Imlach sang it, and there's a suggestion that Archie Fisher was involved in its writing, there does seem to be a Scottish dimension to its origins.
