Watching "Intercourse" at the Back Alley Theatre is like listening to a pop music radio station.

It's a series of short lyrical vignettes - most of them on the subject of romantic love with a sprinkling of soft protest songs. Some of them original enough to be vaguely catchy, some of them are banal and repetitive. Many of them are accompanied by music. Most of them are easily absorbed and easily forgotten.

The show apparently has been styled in the genre of "For Colored Girls . . .," though it is not told solely from a women's point of view. Of the writers, two are female (Joy Jones and Iris L. Morris) and one is male (Ersky Freeman, Jr.). Their poems are shorter and slimmer than Ntozake Shange's in "For Colored Girls . . .," and their show doesn't reach the level of intensity of Shange's.

A group called Pin Points, including the three authors, performs the show under the brisk direction of William Hudley. An effective musical backdrop is provided by an instrumental trio and a row of singers under the direction of Kevin Johnson.

At the end of the show, a "formula for world peace" is unveiled: people should touch each other. The actors shake hands with members of the audience. It's as if a play from the touchie-feelie era of early '70s were being revived. As in so many of those plays, it doesn't work, particularly as it seems to be no more than an after-thought.

For the curious, there is nothing resembling sexual intercourse in the show. Despite some explicit talk, the mood is curiously chaste.
