I can't get the song 4 Main Street Electrical Parade out of my head and I would like to here it!
I have never seen the show either so I don't know where I heard it!
It should be easy enough to find on any file sharing service. I've found versions from paris, orlando, california and tokyo (there are minor differences in the floats in the parades so the music is a bit different in each, as is the introduction.)
