Did Pink Floyd synchronize their song to The Wizard of Oz? See for yourself - long video though (43 mins).
A comment on the video pointed out the similarities:
Man, that effect is just freaky. If you don't want to watch the whole thing, I say the best effects are at: 1:27 (10 seconds) 4:02 (45 seconds) 8:05 (2 minutes) 14:40 (2 minutes 40 seconds) 19:29 (30 seconds) 21:10 (1 minute 30 seconds) 27:41 (25 seconds) 29:10 (1 minute 30 seconds) 32:20 (10 seconds) 37:26 (20 seconds) Add it up, it's still fairly long, but not as long.
I'm glad someone fixed it up for the internet. I recall trying to drop the needle at just the right point in the lion's roar to do this, and it was never easy. Then vinyl went out of style and I wondered how the younger generation does it.

The Wizard of Oz / Dark Side of the Moon alignment may have been intentional after all!
