The Beatles' audition tape rejected by a record label executive in arguably the biggest blunder in pop history has resurfaced and will go on sale at a London auction next week.
Ted Owen of The Fame Bureau, an auction house specialising in pop memorabilia, said the 10-song tape was recorded on New Year's Day, 1962, at Decca's studios in north London.
Paul McCartney, John Lennon, George Harrison and Pete Best - who would later be replaced on drums by Ringo Starr - performed up to 15 songs at the session, 10 of which appear on the tape to be sold on November 27.
The band members had been driven from Liverpool to London the night before, and, despite getting lost on the way managed to get to the studios in time for the infamous session paid for by their manager Brian Epstein.
Decca's senior A&R (artists and repertoire) representative Dick Rowe, who later became known as "the man who turned down the Beatles", decided against signing them in favour of Brian Poole & The Tremeloes, who also auditioned that day.
"Guitar groups are on their way out, Mr. Epstein," he is widely quoted as saying.
Rowe did, however, sign the Rolling Stones, who went on to become one of the biggest acts in British rock, and experts dispute whether it was him or a more junior colleague who passed the Beatles over.
There are bootleg versions of the session in existence, but the "safety master", or back-up tape, on offer at auction is unique, Owen said.
"The most important thing about this is the quality," he told Reuters. "There are bootlegs out there, horrible bootlegs - some are at the wrong speed, others are crackily and taken from a cassette off an acetate (disc).
"This quality we have never heard."
Despite its rarity, the tape has been estimated to fetch £18,000- £20,000, which Owen said had been set by the owner and was a "sensible" starting point.
He added that only a handful of collectors were likely to bid for the piece of pop history, and, given that the Beatles own the copyright through their company, a commercial record release based on the tape was extremely unlikely.
Marked as the "Silver Beatles", which the "Fab Four" were briefly called, the tape comes with a hand-written track list and black-and-white photograph of the musicians posing in leather jackets that would be been used for the record sleeve.
Also on offer at the Popular Culture auction is a guitar used by Jimi Hendrix to play the bulk of his breakthrough set at the Monterey festival in California in 1967. The black Fender Stratocaster is expected to fetch £120,000- £180,000.
