Dark Side of Oz - Ever watch it?

I heard about this few days ago, wanted to share it with everyone right away but was (still am) sick us f. I found out that this has been around forever. They say someone did it in the 80s. So playing a VHS and syncing it with a record. And why would even anyone try it (drugs?)

So the story is, you play The Wizard of Oz and after second or third roar of the lion you play the The Dark Side of the Moon by Pink Floyd and the magic happens. Of course band members said that album has nothing to do with the movie but it is just to much of weird coincidences.

I had no time to watch it whole but the first 30 min
minute:

• 4:00 Dorothy is balancing on the fence and fels. Music: "And balanced on the biggest wave" and cuts exactly when she is falling.
• 7:57 the sound as we see the lady coming for the dog. and the cut is just perfect
• 11:05 Lyrics:no one told you when to run (as we see Dorothy is running away)
• 16:00 the whole tornado scene is just perfect with The Great Gig In The Sky
• 17:11 as she fels to the bed the music slows down
• 19:33 songs ends just before she opens the door and we see the colored part of the movie. as we see the yellow brick road we hear the sound of money
• 28:12 dancing (it just fits :D )
• 29:08 in the song you hear word black echoing and the black witch appears
• 1:39:50 i did skip to the end and as she wakes up we hear the lyrics home, home again.

So any of you heard about this? Watched it? Think it is weird? Or if you play enough music over some movie it is bound that something like this will happen?
