If you are interested in Off-Broadway you might want to look into the Other Josh Cohen. It got strong reviews and a very enthusiastic response by the audience the night I saw it.
Saw this one a week ago and I am telling everybody I know who likes theater to go see it. It is extremely witty and well staged, especially for such a feel good show. And it seemed like the entire audience loved it as much as my wife and I did.
Are there any shows on Broadway or Lincoln Center that do not mic their actors? Saw My Fair Lady last week and I could not detect any. Have they just gotten that good at disguising them?
