Jazz took too much discipline. You have to come in at the right place which is different than me singing the blues where I can sing 'Oh baby ' if there's a pause in the melody. With jazz you better leave that space open or put in something real cool.

Playing and singing at the same time is pretty cool but sometimes it's difficult to know when you can just really let go a bit because you've got to get back to bloody microphone and sing some stuff.

I've never believed in singing about Satan and thinking he's cool because he's not.

I once sang 'Summer Nights ' from 'Grease ' at a bar in Melbourne with John Travolta who's a good friend of mine. He looked cool singing the part of Danny - sitting in an armchair smoking a cigar - while I got stuck playing Sandy.

Music is the greatest communication in the world. Even if people don't understand the language that you're singing in they still know good music when they hear it.

I sing both in my shower and in my car mostly in my car because I have this weird thing - whenever I'm singing to the radio - my friends kind of hate it - but I pick out the harmonies in my head and I'm singing the harmonies to the tracks and I'm jamming it out.

When I'm in the car and somebody comes on the radio singing the high notes I try to sing along.

Like all soul singers I grew up singing in church but sometimes I would leave early and sit in the car listening to gospel band The Blind Boys of Alabama. Hearing their lead singer Clarence made me connect the idea of church and show business and see how I could make a career singing music that stirred the soul.

I always loved music. You know my parents said I started singing when I was 4 in the car.

I don't want a flashy car just something that would allow me to stop using the Tube. And it would be good not to have to rely on my mum all the time particularly when I have to listen to her singing in her car.
