Yea, he'd done Chess at Royal Albert Hall (the one with Idina Menzel, Kerry Ellis, Adam Pascal... that's available on DVD), he's fantastic in it.
I've seen him live in concert, too, and he is just as an amazing singer live as you would hope... and he is really funny which I hadn't known before I saw his show.
I hope he comes to Broadway soon, I don't even care what part. I think his voice can do a lot of things, and he could probably pull off both a dramatic and a comedic part acting-vise... Just cast him in something! ASAP!
