The show crosses lines between a typical rock show and a play. No sets, few props, and no actors other than the band and its singers. If you've seen the movie, you'll see they changed little in adapting it. But it's an intersting way of framing the story.
And a first: after the play is over, if you applaud enough, you get an encore, just like at a regular rock show. We got a medley of "Surrender","I Believe in a thing called love""Communication Breakdown" and a reprise of "Tear me down". Try getting an encore at Pirates of Penzance or Rent!
