I was just getting ready to post this , looks like you found it already, they come in literally hundreds of songs.

Hey! Bruce has been here before! Very nice using the Genny as a jack shaft your getting that Double Reduction.
  I can even recognize the tune! So your speed is very good.
  I think my sketch may still need the double reduction as the big wheel hanging off the side of the Ferris wheel jack shaft (added) likely is still not enough reduction to get down near that 4 RPM range.
  Also Clever: Bruce mounted the movement right to his pressed tin engine base, the thin metal makes a great soundboard! (Amplifier)
