The song in the Drain Cleaner store is "Cell Block Love" from Leisure Suit Larry 6. Also "Consumite Furore" can be heard in Torin's Passage. I wonder if in 1995 Roberta and Al Lowe had some kind of agreement where each of them, in the game that they were designing at the time, had to use a song from the other one's game.

I can't find the "why" to that (haven't searched that long). Al Lowe worked for Sierra at that time (Larry is a Sierra game). He also worked as a programmer on the early King’s Quest adventures (isn't that also from Roberta?). Or maybe you're not asking/looking for an explanation but just sharing. In that case, thanks for sharing. I never played Larry 6. Did play the first one many times, back in those days: Leisure Suit Larry in the Land of the Lounge Lizards. Loved that game. Good memories.
