We had a send-off for Gillian Ayres, no church service, just a semi-institutionalised wake.   It was quite clear that we should have served gin and tonic, not elderflower cordial, because nearly every speaker referred to that as her favourite drink, along with the sixty cigarettes a day.   The President spoke, her son Sam, Shirley Conran, her accountant, a lawyer who collected her paintings:  all made clear what a wonderful, anarchic, anti-establishment, warm-hearted rebel she was, as a person as well as in paint.
