It's about you putting in the work, practicing every day, and hopefully one day you write the song the whole world wants to get down to. And one day you're going to be sitting next to Ellen DeGeneres talking about how you broke records and rocked the Super Bowl!

I don't care what people say about my relationship; I don't care what they say about my boobs. People are buying my songs; I have a sold-out tour. I'm getting incredible feedback from my music.

I've never gotten thick skin. If you close yourself off and you get this protective armor, there is a price you pay with that - of not feeling. And feeling is important when you are a songwriter.

We were four guys... I met Paul, and said, 'You want to join me band?' Then George joined and then Ringo joined. We were just a band that made it very, very, big, that's all. Our best work was never recorded.

We're not Beatles to each other, you know. It's a joke to us. If we're going out the door of the hotel, we say, 'Right! Beatle John! Beatle George now! Come on, let's go!' We don't put on a false front or anything.

It's been my dream since I was a child to somehow unite people of the world through love and music.
