My old school in Liverpool is now a performing-arts school, and I kind of teach there - I use the word lightly - but I go there and talk to students.

There's nothing bigger than being asked to perform at the Super Bowl.

By the time we made "Abbey Road", John and I were openly critical of each other's music, and I felt John wasn't much interested in performing anything he hadn't written himself.

To this day, if I ever meet grownups who play ukulele, I love 'em.

I've got a few guitars that I like. The trouble with fame and riches is that you have more than one guitar.

It's like if you're an astronaut and you've been to the moon, what do you want to do with the rest of your life?

Somebody said to me, 'But the Beatles were anti-materialistic.' That's a huge myth. John and I literally used to sit down and say, 'Now, let's write a swimming pool.'
