McCartney's drug confession

Sir Paul McCartney claims drugs didn't help his songwriting.

The Beatles legend says even though he may have thought so at the time, drugs didn't improve his creativity.

He confessed: "Generally, I'm not sure they have helped. I think you think that they're helping."

Sir Paul, who has just released new album 'Chaos and Creation in the Back Yard', says he prefers to write without drugs nowadays.

He explained: "Drugs are not that cool. I have quite a liberal view, but I prefer to write 'straight' now. It's just the easiest way to do it. Also, you grow up, you know?He added to Britain's Big Issue magazine: "But I prefer to keep a little bit off that subject, if you don't mind. I find that a little bit private these days."
