Richard Rodgers and Oscar Hammerstein may never have imagined “Shall We Dance?” as a comic pas de deux for a towering beauty and her diminutive admirer, nor might they have suspected that one day a lovelorn young lad might pose the musical question, “How do you solve a problem like Maria?” But that’s precisely the kind of invention lavished upon this new revue, with innovative musical arrangements, including a sultry Andrews Sisters-esque “I’m Gonna Wash That Man Right Outa My Hair,” a swingin’ “Honeybun” worthy of the Modernaires, and a jazzy “Kansas City,” proving how terrifically up-to-date the remarkable songs of R&H remain.
