In 1975, Alfred Uhry and Robert Waldman constructed a foot stompin’, knee slappin’ good time with the musical The Robber Bridegroom. It played two short stints on Broadway, one in ’75 (with Patti LuPone) and the other in ’76 (starring Barry Bostwick who won a Tony Award). Since then, The Robber Bridegroom has been mostly relegated to regional and college productions, but a new revival by Roundabout Theatre Company in their Off-Broadway Laura Pels Theatre is so delightful that it makes you wonder why we don’t see this musical more often. What makes this production such a darn good time can be credited to three things: a catchy, energetic score, an ensemble working in perfect synchronicity, and the smart and steady direction of Alex Timbers.
