When John was with me, it was total commitment. Whatever he did outside our relationship didn't seem very important. We were together such a lot of the time that whatever other affairs he had once we met couldn't have amounted to much because I was with him most of the time. He kept me in Liverpool as late as I dared stay.

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

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

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 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.
