Lately, I have been bemoaning the absence of pure joy in musical theatre. In fact, it seems that most Broadway musicals have to be emotionally eviscerating or screaming, over-microphoned, power belting diva battles to succeed. If comedy is attempted, musical theatre has to be salacious, mean-spirited or vulgar. Sometimes it is nice to go to the theatre and just get absorbed in a delightful plot, a comedy of errors with characters who make you smile and songs that stick in your brain because they actually have a melody. Is it any wonder, then, that I find myself in a state of euphoria over The Roundabout Theatre Company’s revival of the 1963 Jerry Bock, Sheldon Harnick, and Joe Masteroff musical She Loves Me.
