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.
Dubbed by Lennon "A Matter of Pee," the missive minces no words and shows the former Beatle's discontent with the recording studio that wanted to evict him over the matter. It dates back to Lennon's "Lost Weekend" period.
"Should you not yet know, it was Harry and Keith who pissed on the console!" Lennon wrote in the exclamation point–laden letter. Later in the note, he added, "I can't be expected to mind adult rock stars nor can "The note will be of huge interest to Lennon and Beatles fans around the world.

Indeed, Lennon and Nilsson were sometimes as bad as each other and famously were ejected from the Troubadour nightclub in West Hollywood for drunken heckling of the Smothers Brothers.
Moon was renowned for blowing up toilets and TV sets and in 1978 died in Nilsson's London flat after overdosing on pills meant to curb his alcoholism.
