At the end of last month the band had said they would be releasing a record called "Flaming Side of the Moon," which was intended to be played at the same time as Pink Floyd's 1973 original. The band said also that the album was "carefully crafted to sync up perfectly with the 1939 film, 'The Wizard of Oz,'" a nod to the theorists who claim that the original album could be used as an alternative soundtrack to the cinema classic.
However, the whole release was a joke, staged by the band in conjunction with comedy website Funny or Die. In a video entitled "The Flaming Lips Sell Out," which you can see below, the hoax is revealed as screen shots of a host of news sources which reported the story are shown.
In 2009, the band released a cover version of "Dark Side of the Moon," which featured guests including Henry Rollins and Peaches.
