John is a central figure in my life. I will always be grateful for having so much intimate time with him. The more distant his stuff becomes, the greater he seems. I used to do caricatures of John. He was the only person I knew with an aquiline nose. When I painted him recently, I found myself saying: ‘How did his lips go? I can’t remember.’ Then I would think: ‘Of course you know, you wrote all those songs facing each other.’
