here's my question about The Wizard Of Oz & Dark Side Of The Moon - did they have a screening room and a print of the film? because they worked on the album in 1972, and betamax didn't come out until 1975, so they would have had no other way of watching it and making sure the music synced up to the film, which basically debunks the theory completely. unless they actually did somehow have a print of the film and a way to screen it.
