The late John Lennon penned a letter titled 'A Matter Of Pee' in the 70s and it was sold by London auction house Cooper Owen to a private collector for £53,000.
The Beatles star penned 'A Matter Of Pee' in the 70s to complain about Keith Moon of The Who and singer-songwriter Harry Nilsson urinating on the studio mixing desk and claimed he left the studio before the incident.
According to The Sun newspaper, the letter was sold to a private collector by London auction house Cooper Owen.
The letter - which he wrote with red ink - reads: ''Should you not know, it was Harry and Keith who p****d on the console!
''Tell (the studio owner) to bill Capitol for the damage, if any?
''I can't be expected to mind adult rock stars, nor can May [Pang]. Besides, she works for me, not A&M.
''I'm about to piss off to (rival studio) Record Plant because of this crap.''
