North Shore Music Theatre’s joyous production of “42nd Street” follows its hit-filled overture with an explosive opening number set in a Broadway show audition in 1933. The star-is-born plot is optimistic and energetic, like the fabulous tap dancers that fill this exuberant cast. (Hey -- Bill Hanney did what? Look for this clever in-joke about the theater’s producer -- it’s projected as a newspaper headline on the opening curtain.)
