A one-joke musical it may be, but Urinetown has so much fun with the joke, not to mention so many other well-aimed satirical and sociological barbs, the overall effect is of something as fresh and urgent as it is laugh-getting. The Brecht-Weill-style tunes click, the lyrics tickle, and the supporting cast (especially Spencer Kayden as a little twerp and Ken Jennings as a Fosse-posed psycho) is a hoot and then some. A dash of second-act cynicism hampers some of the fun, but that's only because the authors really do have the courage of their convictions.
If a little of Urinetown's former off-off-Broadway "let's put on an offensive show" wonderment is lost on the Henry Miller stage, having such a wild, seditious and off-beat tuner make it to Broadway more than compensates. It's still bladderific!
