‘The Gumball Gang: Crime-Solving Kids’

Young sleuths have a venerable tradition, from Nancy Drew and the Hardy Boys to the set of enterprising middle school detectives at the heart of this musical revival from Tada!, the youth theater troupe. Jim Colleran, the show’s author, has set his hourlong romp in Littletown, a surprisingly cultured hamlet that’s home to the Cosmopolitan Museum of Art. When it’s discovered that a masterpiece has been replaced by a fake, the Gumball Gang steps in.
