That's it, karen, and thanks - I knew the Mudcat would come up with the goods. I think the words when I heard the song were a bit different at a couple of points, thus proving that it is now a real folk song.
If anyone knows more about it, I'd be grateful. Like, who is Jim Matthews? (I've sent KNITPICK a message asking) And any suggestions for a tune? I sort of half remember it, but not the half that helps.
And any other broken broken token songs will be warmly received here...
