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

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.

I was proud, excited and a little frightened. It was all taking off so quickly…the more successful the boys were, the further away from me John felt. I was getting used to being a mum, but most of the time I felt like a single parent…it was hard not to feel frustrated with being stuck at home. I loved Julian, but I knew that if I hadn’t had him I could have seen much more of John and that was hard…I felt shut off from the life he was living. After years at his side, I was excluded, just as it was all happening.

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.

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.

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.
