"I'll add that I saw Raul Esparza as the Emcee in Cabaret the same night I saw Polly Bergen, and he was an enormous disappointment. It was his first night back from vacation and he barely seemed awake throughout the show's first act. He did get it together for Act Two, but I still rank that performance as one of my biggest Broadway letdowns."
I'm sorry and surprised to hear that, as I do not believe Raul has a rep for ever giving less than 100 percent. But of course it's possible that even someone like that has a bad night, for whatever reason.
