Audio footage of an old interview with John Lennon, in which he describes the recording of The Beatles' final album as "torture", is set to be auctioned off nearly four decades after it was presumed lost. The Imagine icon conducted the candid chat with Village Voice journalist Howard Smith in Toronto, Canada shortly after the legendary rockers had completed work on their 1969 release Let It Be, and Lennon did not hold back on how torturous the whole experience with Paul McCartney, Ringo Starr and George Harrison had been. In the interview, which also featured his wife Yoko Ono, he said, "We were going through hell. We often do. It's torture every time we produce anything. The Beatles haven't got any magic you haven't got. We suffer like hell anytime we make anything, and we got each other to contend with. Imagine working with The Beatles, it's tough... "There's just tension. It's tense every time the red (recording) light goes on." Lennon goes on to admit the Fab Four "didn't really want to" record the album Let It Be, but adds, "Paul was hustling for us to do it." The tape was recently found buried among the items in Smith's attic at his New York home and it is now set to go under the hammer as part of an upcoming sale by bosses at RR Auction. The lot will be among more than 100 other Beatles-related items up for grabs at the Marvels of Modern Music auction, which takes place online from 19 to 26 September (13). The 'lost' interview has a minimum bid of $300 (£200), but is expected to fetch up to $10,000 (£6,670).
