A previously unreleased demo of David Bowie's 1969 number one single "Space Oddity" with alternative lyrics is set to be aired in a new BBC4 documentary.

The People's History Of Pop is a four-part BBC4 series covering music fans' recollections of 1956-1996.

The first episode, which aired in April, covered the formation of the Beatles and the Rolling Stones.

For the show, host Danny Baker was given access to the unreleased vault of material by Bowie biographer and collector Kevin Cann.

As well as Bowie, the second episode in July will feature Pink Floyd, Bob Marley, Marc Bolan and Northern Soul.

"The show meets music fans, including some who fell in love with the psychedelic sounds of Sgt Pepper, hippies who discovered peace and love at the Isle of Wight Festival, and Black Sabbath fans who turned to the new sounds of heavy metal," a statement regarding the show reads.
