Pink Floyd's David Gilmour is clearing up whether the "Dark Side of the Moon" album was created to synchronize with the "Wizard of Oz."

The rock album famously, and mysteriously, syncs up with the film when they are both started at the right times.

Many years ago, someone discovered that Pink Floyd‘s The Dark Side of the Moon and the 1939 movie The Wizard of Oz will sync up in eerie ways when jointly started at just the right moment. This theory came to be known as “The Dark Side of the Rainbow.

David Gilmour talks about getting rave reviews for his album Luck and Strange, working with his whole family on the album and the rumor that The Dark Side of the Moon was written to synchronize with The Wizard of Oz movie.

David Gilmour was a guest on The Tonight Show Starring Jimmy Fallon on Thursday night (November 7) and the former Pink Floyd guitarist/singer addressed the widespread theory that the band's 1973 hit album Dark Side of the Moon was purposely written to sync up to The Wizard of Oz.
