Wow, I struck gold! George, thanks so much for answering. To be honest I don't remember what year the recording is from, but I can look it up next time I come across my files (we recently moved and they're still in boxes). I think the recorder probably got turned on just as you started the first chorus. Thanks for the first verse, it clarifies a lot.
And thanks for bringing the song into being in the first place. I for one have been enjoying it for years, and my little son (18 months) likes it too. It must have struck some chord inside, because I catch myself singing bits of it absentmindedly, and it's never been out of memory long enough to be forgotten.
Oh, just so you know, the family named a schipperke (little black flemish dog frequently used on canal boats; a spitz breed) after this song; we called her Molly but her full name was Molly-Come-Back. :-) (She's still alive and well, but we kids all left home and the parentals split up, and she went to live with a more together family)
I know your name; you've been to Mystic more than once, haven't you??
