There are tales, still told by the old ones of Broadway, of a time when Charm - with a capital C - was a cardinal virtue in the theater...To my great surprise, a brand-new version of such a play has materialized at the Samuel J. Friedman Theater, and it is, in a word, charming. It is also smart, sad and so impossibly well-spoken you may feel like giving up on conversation. It is called 'The Assembled Parties,' written by Richard Greenberg and featuring a leading lady, Jessica Hecht, who is charm - I mean, Charm - incarnate...'The Assembled Parties'...is an elegy to a breed of woman, a style of living and a genre of theater of which only vestiges remain in frantic, self-promoting New York. Directed with loving care by Lynne Meadow, this is an old-fashioned play that ruefully knows that its time has passed and, moreover, why it's passed.
