In a recently unearthed interview with John Lennon, the former Beatle describes just how fractious the working relationship between the Fab Four was.

As per the Telegraph, the original interview - conducted by New York Publication the Village Voice - was conducted just after The Beatles had finished work on 'Let It Be', an experience which Lennon described as "hell."

The interview, by Howard Smith, lay forgotten about in his attic until recently and will now be put up for sale by RR Auction.

Lennon, who was joined by Yoko Ono at the time of the interview, said to Smith of 'Let It Be': "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."

He continued: "There's just tension. It's tense every time the red light goes on. We never really finished it. We didn't really want to do it. Paul was hustling for us to do it. It's The Beatles with their suits off."

The interview is expected to reach somewhere in the region of $5,000 to $10,000 at auction.
