I’ve heard that he had some weird sort of “mother fixation” with Yoko Ono, actually called her “mother” all the time even though they were lovers. I always thought that was pretty creepy too, and at the time that Yoko helped to break up the Beatles she had some weird hold over Lennon that didn’t seem like anything in the “normal” range of romantic love (whatever that is). The rest of the band couldn’t stand her. A lot of people were creeped out by “John & Yoko” because they did not think it seemed like a healthy adult peer-to-peer relationship, but rather something that filled some desperate needy void in John Lennon’s psyche.
I wonder if John had Yoko dress up in Mommy’s clothes before they ‘did it’.
