“He’s a high tenor with a three-and-a-half octave range. He goes from basso low E up to G and A-Flat above high C. A lot of people think its falsetto, but it’s not. It’s all connected, which is remarkable. During his vocal exercises he would put his arms up in the air and would start spinning while holding a note. I asked him why he was doing that, and he said ‘I may have to do it on stage, so I want to make sure it’s possible.’ I’d never seen anything like that before. I thought maybe I should stop him so he can concentrate on his voice now, and dance later. But I figured if he can do it, let him do it.”
