Beatles collectors will be pleased to know that some rare, never-before-seen John Lennon memorabilia will be put up on the auction block. And its origin story is nothing if not interesting! 

According to Rolling Stone, back in the 1970s, John Lennon wrote a letter to producer-turned-murderer (oy...) Phil Spector, blaming the late Harry Nilsson and The Who drummer Keith Moon for peeing on a console. Of the situation, the late Beatle felt slighted that he was evicted from the premises and minced no words when it came to his opinion on the matter.

"Should you not yet know, it was Harry and Keith who pissed on the console!" Lennon wrote. Later in the note, he added, "I can't be expected to mind adult rock stars nor can May, besides she works for me, not A+M! I'm about to piss off to [recording studio] Record Plant because of this crap!" 

Ah... letter-writing. Remember those long-begone days? These days, this type of thing would be taken to Twitter. Doesn't have the same effect now, does it?

In any event, according to Freep.com, this letter -- which is part of a series of letters that also includes doodle drawings signed by Lennon on the front and Yoko Ono on the back -- has gone on the auction block as of today. It dates back to his "Lost Weekend" phase, and auctioneer Cooper Owen has it on its website. 

"This is a rare note in that it mentions so many well-known figures from the era," auctioneer Louis Cooper said. "Clearly John Lennon is blaming Keith and Harry for urinating on the console, and he also announces that he is about to leave the record company ... In it, he seems quite irritated."
