Dark Side of the Rainbow

Earlier on, I thought I would try synching the Wizard of Oz film up with Pink Floyd's "Dark side of the moon" album.
I had previously tried this, but was distracted as I think I was ill at the time.

I think I got it right this time - starting the album when the MGM lion roars for the first time - because some of the things really do seem to match up!
I noticed most of the things that are listed on this site, it was quite interesting :)

I do wonder though, how on earth did someone figure all that out in the first place?!
