Hey Helen, apologies for the silence. It's been rather hectic over at my workplace and also in trying other avenues for this inquiry I neglected to check back here. So yeah, I tried my luck in a few other places, the session being one of them. So far there's still nothing.

Regarding your suggestion, while I agree that there are some similarities, I don't believe it's Jokes, Jokes, Jokes. Honestly I'm starting to think that your original theory of it being an original composition just for the game is correct.

My last ditch attempt at finding an answer to this is contacting David Gossage. He was the producer/arranger for all of the traditional music for the game. I sent him a message on his website a few days ago but he's yet to respond.
