Dark Side of the Rainbow

For anyone who has ever been curious about syncing Pink Floyd's Dark Side of the Moon album with the Wizard of Oz. Here it is, all the hard work done for you!

From the YouTube description:
In this 1st of 6 videos watch as Dorothy balances on a fence rail while the words "Balanced on the biggest wave you race towards an early grave" are sung. Dorothy falls as the words "early grave" are sung. Watch how the tempo of the music then changes to work with the movie.

This is just the beginning; it gets much better.
