Supposedly (I've never tried it) if you play the Pink Floyd Album "Dark Side of the Rainbow" 2.5 times on loop during the Wizard of Oz movie, with the movie muted, you will notice that the album on loop seems to be synched with the movie. This is odd because it's on loop, meaning that the same music fits more than one scene perfectly. It's said to be a coincidence but I think they did it on purpose. Here's a clip that somebody made on YouTube that shows the tornado scene with the Pink Floyd music over it. YouTube - Pink Floyd-Dark Side of the Rainbow 3 (There are a bunch on the "Related videos") Here's another: YouTube - Pink Floyd-Dark Side of the Rainbow 7 Seems like a major coincidence (if it truly is a coincidence).
