Yoko had 10 years and I had 10 years and I would rather have had the 10 years I had than the ones she did. I had the raw talent and the raw human being, before the sycophants arrived.

The first thing Julian wanted to do in life, well, before he wanted to be an artist and then a musician, was to be a chef. He'd come home and say 'Why don't you bake cakes like my friends' mothers?' I'd say, 'Oh, Julian, go out and buy a Mary Baker cake mix and do it yourself!' That started him off! By the time he was 13, he'd disappear into the kitchen whenever we had visitors and emerge with beautiful canapes. Now he thinks nothing of cooking for ten or 15 people, and he does it so calmly.

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

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'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 an extraordinary man. Our relationship has shaped much of my life. I have always loved him and never stopped loving him. That’s why I want to tell the real story of the real John – the infuriating, lovable, sometimes cruel, funny, talented and needy man who made such an impact on the world. John believed in the truth and he would want nothing less.
