The new 1950s-set musical Cry-Baby, featuring a score by David Javerbaum and Adam Schlesinger, started preview performances on Broadway tonight. Like the Broadway (and Hollywood) hit Hairspray, Cry-Baby is also based on a John Waters movie, and it also has a book by the Hairspray writing team, Thomas Meehan and Mark O'Donnell. Cry-Baby will have its official Broadway opening at the Marquis Theatre on April 24.
