The item is being sold by Kevin Hutchinson who was given the tape by Ronson prior to the guitarist’s death in 1993. According to Hutchinson, he had forgotten all about the demo and it had been lost in his loft for almost 50 years.
“Now I’m 65 and I played it, I just couldn’t believe how good it is,” Mr Hutchinson told the Press Association.“But at the time, I thought: It’s not bad.
“At 16 you’re not totally impressed, nothing impresses you,” he added.
The recording, being sold on March 12 by Omega Auctions, has been given an estimate of £10,000 by the auction house. “In consultation with a Bowie expert, we can say with confidence that this tape contains a very early and possibly the first ever demo version of Starman,” Dan Hampson, assistant auction manager at Omega Auctions, said.
“There’s a lot of Bowie mythology around the writing of this timeless classic, and the raw and truly beautiful version heard here helps to provide a fascinating insight into the creative process of a bona fide genius.”
