"I mean, we're all human, and sometimes we feel very communicative and sometimes we don't. But most of the time, if I'm not feeling good and then we get up on stage, I just look at somebody in the eye and just say, 'Hey, I need your help tonight.'

"I mean, I'm not asking them directly, but through the eyes I'm asking them, 'I need your help.' And they give it to me, somehow."
