Back in March 24th in 1973 Pink Floyd released Dark Side of The Moon on this date in the UK. The album has sold over 35 million copies to date. For other interesting facts (30 in total) go to the official website.
In honour of this celebration, Bigger Pants presents part 4 ("Money") of the Dark Side of The Rainbow. This is the mashup of the Wizard of Oz and Dark Side of The Moon that works but all members of Pink Floyd say it's a coincidence.
