Former Beatle Sir Paul McCartney has found a way to deal with fame, by making up rules for himself.
"The weight of fame can get pretty annoying, but do you know what I do now? I have rules. I've finally grown up and finally realised I've got rights," he says.
"So people come up to me in a restaurant and say, 'Can I have your autograph?' and I say, 'I'm really sorry but I don't do that when I'm eating. I hope you understand," he tells BBC Radio 4.
"Shopping is another. 'I'm really sorry - I'm shopping.' I'm looking for some nails and they've got to be three inches long for the job I'm doing, and there's no way I'm going to find them when I'm chatting to you and having my photo taken."
