I think that people who have Vegas throat are people who sing from their throats only.
But I don't work out. I pay people to do that for me.
I can tell jokes. I can talk to the audience. I can relax. I can change my songs whenever I want. I can change the tempos. I can change the mood, because I'm in charge.
I've been a boxing fan ever since I was a kid.
I only eat one meal a day. Lunch, not dinner.
When I sing full-on I use my whole body. I open my throat and let it fly out.
