“In the last week, three shows headed for Broadway – the long-gestating Stephen Sondheim-John Weidman musical “Bounce” in Washington, D.C., the Barry Manilow-Bruce Sussman musical “Harmony” in Philadelphia, and Nancy Hasty’s play “Bobbi Boland,” which had already begun previews at the Cort Theatre – closed before opening here to critics and audiences. New York-bound projects failing are not uncommon, but three high-profile shows in a row facing this fate is most unusual.”
