I got it from a CD I bought at Disneyland a few months ago. It was a two CD set, but I can't recall the name right now. I do know it wasn't the 50th CD, but I know I have seen it quite often at the World Of Disney in Downtown Disney.
I have the parade of dreams audio and show stop music if you would like it. I have the float break down audio a show through with the original uncut version, and the show stop they use now (my own edited version to sound like what they use now)
