Dance.

Katherine Dunham is an anthropologist-dancer who went to Hollywood, but her current program at the Martin Beck Theater suggests the sequence in reverse. Her "tropical revue" is high-toned hot-stuff and it goes over big with an audience that gets a kick out of sex brought into the parlor by a dancer who is obviously a lady. For her dances Dunham has used primitive and folk material from the Pacific, the Caribbean and North and South America. Now there are three ways in which such material can be presented in the theater.
