Yep, that song is about her.
“That song is about her”.
Sure, his mother was the “Julia” of the song, but the song is about Yoko. “Ocean child” is the English translation of “Yoko Ono”.
Maybe I’m getting inured to shock, but I don’t find this so terrible. Lots of teen boys have confused thoughts around that age. And Julia wasn’t a mother figure to him, she farmed him out for his Aunt Mimi to raise - John said that she was more a friend to him than a mum. His childhood, and her death when he was 18, definitely screwed him up though. Like all liberals, he had something to hide. I hope he rests in peace.
