One of the most famous urban legends in rock music is 'The Dark Side of the Rainbow.' It claims that Pink Floyd’s 1973 masterpiece, 'The Dark Side of the Moon,' was intentionally recorded as a synchronized soundtrack to the 1939 film 'The Wizard of Oz.' Fans claim that dozens of coincidences occur when the album is started at the third roar of the MGM lion, such as the music changing tempo as Dorothy begins to run, or the song 'Brain Damage' playing during the Scarecrow’s 'If I Only Had a Brain' sequence. Band members, including David Gilmour and Roger Waters, have consistently denied any intentional connection, calling it 'pure coincidence' and noting that they didn't even have the technology to play the film in the recording studio. Regardless, the theory remains a popular pop-culture phenomenon.
