David Bowie’s first-known studio recording, which was rejected by a record company and found in a bread basket, has been sold for nearly £40,000.
The 1963 demo tape features a 16-year-old Bowie, then David Jones, in his first band The Konrads.
The group was turned down by Decca and the tape of Bowie singing I Never Dreamed was never released.
Bowie quit the band in the following months, but his career took off six years later with Space Oddity.
On Tuesday, at an auction in Newton-le-Willows, the tape fetched £39,360 from an overseas collector.
It had been estimated to sell for £10,000, but Director of Omega Auctions, Karen Fairweather, described the sale as a "bidding frenzy."
Also sold were promotional sketches drawn by Bowie when he was in The Konrads.
Along with photographs and band documents, they sold for £17,130.
The tape and memorabilia was discovered by former Konrads’ drummer David Hadfield, who also managed the band.
He unearthed it, while moving house in the 1990s, in the loft of his garage, in a bread basket which once belonged to his grandfather.
Bowie was the band’s saxophonist but it was decided that he should sing lead vocals for the tape.
Hadfield said: "David had no inclination to become a singer at this point, his heart and mind were focused on becoming a world class saxophone player.
"Our agent, Eric Easton, who also managed the Rolling Stones, asked us to do a demo so he could try and get us an audition at Decca.
"So in early 1963 I booked into RG Jones’ small studio in Morden.
"In preparation for the demo, David and our guitarist Neville Wills wrote two to three songs. We had decided that we would do a couple of guitar instrumentals and one original song."
Hadfield continued: "I chose I Never Dreamed as it was the strongest, the other two were a bit weak.
"I also decided that David was the best person to sing it and give the right interpretation.
"So this became the very first recording of David Jones (Bowie) singing 55 years ago. There is no other recording of the demo featuring David as lead in existence."
Bowie died in January 2016, two days after his 69th birthday.
