The story is more complicated than Freddie Seamen's comments. Fred Seamen was a gofer for the Lennons. He was a good, solid employee. But, Fred Seamen after Lennon died stole the diaries and kept them (guess where) in his Brooklyn apartment. Why? In his own warped thinking, he wanted to free them from Yoko and give them to Julian.
Duh? He stole them so he could sell them and write a book and make money.[:(!] Yoko did the right thing and had the cops rightfully arrest Seamen. Look, the man stole personal property that was rightfully Yoko's and he's a thief and a liar.
He exaggerates a lot of what happened with the Lennons and was the source for many of Albert Goldman's distorted biography. In the Goldman distortion, Lennon was made out to be an anorexic masturbator who kept his urine in mason jars or something. Totally not true. It was said he was strung out on heroin and he occasionally would kick his baby. Again, not true.
While i never believed Lennon's tall tales to Playboy, i never picked up a guitar in five years (How many pictured have we seen of Lennon playing guitar '75-'80), (Free as a bird in 1977)...or that he baked bread all day and played with the baby all the time (Lennon was not a man of routine)....I think the real truth somewhere right in the middle between Lennon's warped exageration of Mr. Mom and Goldman's wacky eccentric flaky Lennon being consumed by Yoko's imprisonment.
