We first recorded the song, sung by Jack O'Connor, in Morris Blythman's living room, Glasgow, on an old EMI tape recorder. Pete Seeger took the tapes to Mo Ash of Folkways and it was issued on the LP Ding, Dong, Dollar.
The pipe tune Hamish set his lyrics to, The Bloody Field of Flanders, was composed by John A MacLellan who died in 1980 so it is still in copyright.
I suggest, Joe, that you contact the School of Scottish Studies, Edinburgh, for details. Or maybe Jack Campin knows.
