In our review of the Broadway premiere of American Idiotin April, we wrote that the spectacle consists of "a lot of apathetic whining, self-pity, and drug-fueled degeneracy passed off as 'punk.'... And the tinny score, at once anthemic and trite, sounds like it was assembled in a jingle factory by stoned teenagers convinced they were making something profound for the ages." But Green Day fans have been eating it up, and now they're due for seconds, because frontman Billie Joe Armstrong will be joining the show for eight performances from this Tuesday through Sunday. Arts Beat reports that Tony Vincent, the actor who plays creepy emo drug kingpin St. Jimmy, is leaving for two weeks "to deal with a family matter," and Armstrong will step in for the first week of his absence.
