I don't know much about Rock of Ages, but Don Stephenson's performance as John Adams at the Papermill Playhouse was quite possibly one of the worst performances I've seen on stage (along with Antonique Smith as Mimi in Rent). He was completely devoid of charisma and had such an odd manner of speech. For the audience's sake, I hope "Hertz" is a small role.
Stephenson also sent a bitchy form letter to reviewers who dared to criticize his performance in 1776. Nothing worse than an egotist who isn't actually
good.
Let me watch your toes and fingers twitch.
