A vitriolic letter from John Lennon to Paul and Linda McCartney has sold for $29,843 at RR Auction in Boston.

A lucky, anonymous, Beatles fan picked up this enlightening piece of memorabilia which provides great insight into the much-discussed acrimonious split of the legendary pop group in the early 1970s.

The letter, which appears to be a response to an equally cross jointly-written letter from Paul and Linda, expresses Lennon’s disappointment at a lack of acceptance for his and Yoko Ono’s relationship, and an exhausted attitude towards working with the Beatles.

“I was reading your letter and wondering what middle aged cranky Beatle fan wrote it (sic),” Lennon opens. “I resisted looking at the last page to find out. I kept thinking who is it, Queenie? Stuart’s mother? Clive Epstein’s wife? Alan Williams? What the hell—it’s Linda! Who do you think we/you are?” He goes on, apparently incredulous at the criticism leveled against him by the McCartneys.

“The ‘self-indulgent doesn’t realize who he is hurting’ bit—I hope you realize what you and the rest of my ‘kind and unselfish’ friends laid on Yoko and me since we’ve been together.”

Thought to have been written in 1971 as a response to a letter from Linda McCartney who was criticizing Lennon for not having publicly announced his departure from the Beatles, the letter claims he felt that all the members of the band were as tired of it as he was and that Paul himself had advised him not to do so.

“I’m not ashamed of the Beatles (I did start it all) but some of the shit we took to make them so big—I thought we all felt that way in varying degrees—obviously not,” Lennon writes in the typed draft complete with annotations in pen.

Lennon then goes on to express his disbelief at Paul’s agreement with many people that the Beatles changed music and “art” forever.

“Do you really think that most of today’s art came about because of the Beatles? I don’t believe you’re that insane Paul—do you believe that? When you stop believing that you might wake up. Didn’t we always say we were part of the movement, not all of it? Of course we changed the world—but try and follow it through. GET OFF YOUR GOLD DISCS AND FLY.”

Ouch! (But, could this well-meant jibe be the inspiration for the band name “Wings?”)
