Q: You've played in Las Vegas a number of times. How is playing here different from playing elsewhere?

A: You always light a fire in everybody's ass when you play the shows in Vegas because you know they get so many unbelievable shows that you need something spectacular. So you amp up the band more, you amp up the dancers more, you amp up the production crew more, and it's like, OK we gotta compete with “O.” But Vegas is Sinatra and Martin and Davis. You associate it with the Rat Pack and you're talking about the consummate entertainers. You have to entertain when you go to Vegas.

Q: You've put in some memorable performances here, including the time you played the Billboard Music Awards with a broken foot.

A: That might actually be my favorite Vegas performance because I was supposed to sit on a stool the whole performance and I could not stand it. I had to get up. We were doing the performance of “Cry Me A River” and I had a choir and an orchestra. We arranged it like that because I had a broken left foot. But I couldn't stand it, I just had to get up.

Q: Where do you hang out when you're in Vegas?

A: I like to buzz around in Vegas, you know? I've had really good luck at Mandalay Bay.

Q: What's your game?

A: Blackjack. I'm not the type to throw a bunch of money on the roulette wheel because all of a sudden it's gone. I'm not a huge gambler. But I do like to play blackjack. I can sit there and play for hours and maybe you win some or you lose some.

Q: We're doing this interview on a day when you are booked from sun up to way past sundown. How do handle the constant swirl of activity?

A: There are things you can control, there are things you can't control. The madness, the hype, you can't control that so you gotta be able to just roll with that.
