Alas, I am caught out. It came from one of those illicit tapes that so make Gordon Bok froth. He sang it. He hates hand held tape recorders; bans them from his performances...and yet, someone unnamed made a tape of him live, and this song was there. I don't believe he's found the internet yet, so we are safe for a bit...
I believe you can write him at Timberhead Music and ask for the words, and I seem to recall they were in the Forum at one point, but I can't get Forum Search to boot right now. If you want to try, Bob, put a key word or two in the body copy box. I picked "gammon" so as to not get all the St.Pat songs, or all the Puff the Magic...threads.
Blessings,
Barbara
