The story line is as tiresome as the polka music insistently played by an onstage band.

With an onstage band (a really sharp one, by the way), the enterprise is stranded somewhere between a fully staged musical and a concert.

Green Day will not appear in the production, but the show will have an onstage band.

Before they can be killed, the onstage band starts playing to distract the zombies.

But the music, soulfully performed by a six-member onstage band, has a fluid life of its own.

The show also had an onstage band.

(The onstage band that follows her wayward performances is terrific.)

The whole score is played fervidly by a more than competent, if not flawless, five-piece onstage band.

While the music and the onstage band are agreeable, the score seems irrelevant to the show's milieu.
