I think it's something to do with the structural quality of the songs. We weren't actually trying to make stuff that was cool, or of the moment, although a lot of it was. We were trying to make stuff that was good enough to stick around and lo and behold, it has.

I used to think that all my Wings stuff was second-rate stuff, but I began to meet younger kids, not kids from my Beatle generation, who would say, We really love this song.

It comes in handy in situations like that. People always expect you to be riding around in stretch limousines all the time, but I will sometimes take public transportation if it's convenient, and it does surprise people, you see the heads turn.

My brother's researched our early family history. He found a letter from a fella who said he used to be in love with my mum.

I can't deal with the press; I hate all those Beatles questions.

It (LSD) opened my eyes. We only use one-tenth of our brain. Just think of what we could accomplish if we could only tap that hidden part! It would mean a whole new world if the politicians would take LSD. There wouldn't be any more war or poverty or famine.

Most people don't know that I invented the selfie.
