This is actually really cool, more entertaining than watching the guy from the police academy movies roller skate around with a transistor radio in that dodgy movie.This is funny because I was watching this fellow play YMCA on this 1900 era crank organ. It's the size of a minivan, and he programmed the punched tape that makes it play. This one had a thick tape, folded like a fan-book, made from waxed cardboard.
YMCA starts about 3:25 as they put in the "book".
