I didn't marry a Beatle, I married a broke student who played the guitar and ponced all my grant money off me for fags.

John was in constant need of proof of love and security and he was constantly testing people for that proof.

I knew the man up until our divorce - after that I didn't know the man, but it didn't stop me caring about him and worrying because of the complete change that I saw in him. He'd lost his sense of humour and he got aggressive; he wasn't for the world any more, he was just for Yoko. Before that he opened his arms and embraced the world with his wit and humour - afterwards he was a completely different kind of person.

We were both sort of bowled over by the fact that we were married. It wasn't a question of 'Have we done the right thing?' It was all perfectly natural that we should be together. But John didn't get a real chance to be first a real husband or later, a real father. Once he got on the Beatles bangwagon he couldn't get off, even if he wanted to.

John needed to escape his reality. I understood completely but I couldn't go along with him.

Ringo had this habit of lighting up two cigarettes, one for Maureen at the same time that he lit his own. I remember thinking it was a loving thing to do and wishing John did it for me. But that would have been too obviously demonstrative, maybe, for John.

John was closest of all to Paul; their relationship was very complex.
