The first-known recording by David Bowie, when he was the 16-year-old singer of a band called The Konrads, sold at auction in Britain this week for nearly £40 000 (about R782 000).
Music specialists Omega Auctions, in northwestern England, said “a bidding frenzy” around its memorabilia sale led to the demo tape fetching around four times the expected price of £10 000 when it went under the hammer.
It sold for £39 360, Omega said in a statement posted online.
The tape was discovered earlier this year in a loft, Omega had previously revealed.
The song – I Never Dreamed – was recorded in a studio in 1963 when The Konrads asked the young Bowie, then known by his given name David Jones, to sing lead vocals.
Promotional sketches by the then largely unknown Bowie, along with photographs and band documents, also sold for £17 130.
At he same auction, an early The Konrads poster from 1963 went for £6 600, Omega said.
Bowie left The Konrads shortly afterwards and did not achieve stardom until six years later when, already a solo artist, he released Space Oddity about the fictional astronaut Major Tom.
Bowie earned a reputation as one of the most innovative voices in rock over a half-century career.
During his tenure in the industry, he experimented with soul, disco, jazz and ambient music.
He died in 2016 from an undisclosed battle with cancer, two days after releasing his final album on his 69th birthday.
Other items auctioned this week included a fully signed album of rock band Led Zeppelin, which sold for £14 000, and handwritten lyrics by Jimi Hendrix from around 1970, which fetched £10 800
