Well, there's just some universal truths in a way that I've just observed to be true. You read Voltaire. You read modern literature. Anywhere you go, there's these observations about romantic love and what it does people, and these rotten feelings that rarely are people meaning to do that to each other.

When you say something or sing something enough times, it becomes a self-fulfilling prophecy. It's almost like casting spells. I don't mean necessarily in the flighty, 'I'm going to go buy a cloak with a hood now' way.

I'd been touring for so long, seven years. For a year and a half I'd just been curious about what it was like not to tour. It's like if you were to lift a 100-pound barbell with your right arm for seven years, eventually you'd get really curious about what your left arm was capable of.

When I did '1,2,3,4' on 'Sesame Street' they'd rewritten the song and made it about counting. At first, I balked. I was like, 'Counting to four? That's where we're going with this?' Then they sent me appearances by other people like James Blunt doing 'You're Beautiful' as 'My Triangle.'

So, I'm on 'Sesame Street,' walking around with all these monsters, Elmo and his buddies, a whole bunch of chickens, a whole bunch of penguins and a number four dancing about. It was just pure joy, simple, ridiculous fun, stupid joy. There's no irony. 'Sesame Street' is just a crazy great place to be.
