David Bowie: Life on Mars, 1973

Directed By Mick Rock, July 1973.

"Life on Mars?" is a song by David Bowie first released in 1971 on the album Hunky Dory. The song, which BBC Radio 2 later called "a cross between a Broadway musical and a Salvador Dal painting", featured guest piano work by keyboardist and Yes member Rick Wakeman. When released as a single in 1973, it reached #3 in the UK and stayed on the chart for 13 weeks. The song re-entered the UK charts at #55 over 30 years later, largely because of a TV show by the same name that used the song.

In February 1999, Q magazine listed the single as one of the 100 greatest of all time, as voted by the readers. It has continued to chart in the Q 'best of' polls, featuring most recently in 2006 at #45. A BBC Radio 2 poll in 1986 crowned it as the best David Bowie song of all time.

As early as 1974 Barbra Streisand released a version of the song on her album Butterfly. The song has also been covered by Italian artist L'Aura and by pop artist Mig Ayesa and American pop musician Michelle Branch.
