Sharon Playhouse’s joyous production of the 1950 “Guys and Dolls,” one of the greatest American musicals of all time, opened last Friday, July 29 with the exuberance of a Broadway premier at a jam-packed Bobbie Olsen Theater. It’s the first full production staged in Sharon’s updated, old summer-stock barn since the pandemic, which gave the evening a special buzz. And the show’s score by Frank Loesser, one of the all-time great musical comedy composers and lyricists, is chockablock with some off the most popular songs that came from Broadway—delivered with vocal authority by a sparkling cast. But what really distinguishes Sharon Playhouse’s production is the tap choreography by director Justin Boccitto, who renders this Broadway classic into the non-stop, vivacious musical fable it was meant to endure as.
