I haven't seen Wayne's performance in whole, but based on the Broadway on Broadway airing, he has a great voice for Billy. And I've seen him on Who's Line and he is great comedic timing and improv skills. It's amazing how he can hold in his laughs sometime-you see him cracking up one moment, but the next, when his turn comes up, he is calm and ready with a joke.
