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.

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

John's relationship with each of the other Beatles was different. He was at his most relaxed with Ringo, who often had him in stitches with his jokes.

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

Noel [Charles, husband] and I love cooking. He does his cooking and I do mine. I'm the traditional English cook, with a twist now and then. Because I was married to an Italian, I'm also pretty good at Italian food. Noel, he can cook anything, so can Julian.

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 asked me to dance and I nearly died. Bingo! I then amazed myself by being very cool, calm and collected outwardly-inside I was out of this world. The dance was slow and smoochy. I was aloof and John, I think, was slightly embarrassed. It was all very painful and beautiful at the same time. The remaining students were looking on with puzzled expressions at such an unlikely combination.
