Mick, an absolute long shot for you. I have a teeeeny inkling that I saw it in a collection called (ish) 'Songs and Ballads From The Pubs of Ireland', by Healy (Vols I and II). I don't have quick access to a copy, but if someone else would care to check please in order to put us all out of our misery.
If that doesn't work I'll have to pull out the big guns.
Regards, John
