I'd be curious to hear how he got into musical theatre in the first place. Writing I can understand, acting in plays I can understand, but he doesn't seem especially suited to being in musicals with tricky scores. Edna in Hairspray is such an easy role to sing, and he somehow made Tevye work, but hearing him sing I Am What I Am now gives me serious doubts. A great actor he is, but a great singer he is not. And I'm sure he knows this. What makes him keep doing musicals?
