I feel, as a songwriter, it's one of the hardest things to do - to sit down and say how you feel.

I don't try and be dark, but there are obviously darker emotions that I want to capture sometimes.

I definitely don't plead guilty to being a heartthrob.

I'm a big fan of the young 1950s Elvis when he would just go onstage and control the whole environment.

When I see your face, there's not a thing that I would change 'cause you're are amazing just the way you are.

My dad was into the 1950s doo-wop era. If you look at those groups, or at James Brown, Jackie Wilson and the Temptations in the 1960s, you'll see you had to be sharp onstage.

And when you smile, the whole world stops and stares for a while
