And of course Paul during Lost Weekend period seemed to think John was better off than Yoko - even though he (and Linda, for that matter) really didn't like Yoko. He must have had reason for thinking that.

I know Yoko said that she had a heroin relapse sometime during the househusband years - I'm not even sure John knew about it. I am really unsure about a lot of what went on those years. They were so disconnected from everyone, and it seems like the people they did have close contact with were pretty messed-up and untrustworthy themselves. What was Albert Goldman's source for that claim?
