I really like "Promiscuous," actually. My friend Socrates, who's a rapper, performs it with me. It's at the end of the show and it's so liberating and unpretentious — it's just about fun. I feel like I'm 13, dancing in my room to Salt-N-Pepa or something like that!

I've been touring for about eight years now, and after a while you do start to see things in each city. Last time I was touring Europe, I went to the zoo with my daughter. They had this really interesting underground museum with every type of creature. You could see behind the scenes of how they took care of the animals, what they fed them, and how the kitchen cooked their food. It was interesting!
