Thank you for your help, Cattia and Monique; your knowledge here is indespensible.

It's too bad neither of the two people who seem to be searching for the song posted any lyrics or verses to the song to help with identification. It'd sure help me feel more confident that the case is now solved or not. Jeff may be unlikely to return, but perhaps MU will?

Cattie, the hints that it's a somewhat bawdy song make me all the more curious. It's possible two grannies wouldn't sing a risque song to their grandchildren, but then again, if the meaning is veiled enough, it's possible they would!
