freak of the week

Alright, I'm back on my shit, and am once again soliciting advice so I don't look like a total numbskull. I'm currently writing something based off of what I was talking about in a previous post, but the gist is instructing musical variety via a character with outside knowledge into a society who barely got past the drum and basic singing.

Hey, so relating to the previous post I need help finding songs from the 1970s-2008 that have the extremely niche position of being both feasible in a live setting and not requiring any electronic implements, any level of niche or strange is acceptable, and preferred, and as a bonus either fit very well or very poorly into a setting with minimal musical culture and understanding of modern metaphors.

I was wondering if anyone knew of any instruments appearing in the game, as I was struck with an idea relating to the introduction of music into the setting. However, after several hours of feverish searching, the only daigetic music I could find includes humming, a radio (???), bells, and the weird living accordion that Brumm uses.
