[Being judge] is about being honest and giving everybody a fair shot and telling them what you think. Sometimes it's good and sometimes it isn't. It's more important to be honest than say things to make people feel better. I don't think you have to be rude, but I think you have to be honest. But I think it's really important to be specific: Here's what you did that was great and why. And here's what you did that wasn't great and why.

There's some things I can't write about, just terrible personal tragedies.

I'm a big fan of [Frank] Sinatra, he was the best at what he did. The last thing I do is model my career after him, though, because we do different things. He was a great singer and a great actor ... It never crossed my mind to emulate his career, because we have different interests.

When I did the album for 'When Harry Met Sally,' I found myself out there in front of this big band, which I had no idea how to do, and they wiped the floor with me. It's a very specific skill, and I didn't know how to do it.

A lot of the music that you listen to now is because of the things that the Meters did, the Neville Brothers did, and they're there, the guys who invented those beats that the guys sample today. Such an enormous opportunity.

You basically have to play everything (in New Orleans), because you're getting calls to play gigs of all different styles, from classical to R&B to funk; modern jazz to traditional jazz.

I've been all over the world. I love New York, I love Paris, San Francisco, so many places. But there's no place like New Orleans. It's got the best food. It's got the best music. It's got the best people. It's got the most fun stuff to do.
