Rare David Bowie songs to be auctioned - listen to snippets

A reel-to-reel tape featuring three unreleased David Bowie demos will be auctioned later this month in England. Bowie recorded the demos for his debut album in 1967, but none of the songs made the final cut. The tape includes the 'Did You Ever Have a Dream' (which landed on Bowie’s 1981 compilation 'Another Face') and three unheard tracks - 'Funny Smile', 'Pussy Cat', and 'Bunny Thing'. The tape is expected to sell for more than £10,000. Listen to snippets of demos on CNN.
