Isn't that freaky how it all goes together???
It sure is. Very weird coincidences happening through it. I really don't think it was intentional on Floyds part, but its neat, plus I never get sick of hearing Dark Side of The Moon.
But one thing that does make it slightly possible, was that Floyd did a few soundtracks to movies, but then again they are denying the synching to The Wizard of Oz.
