It is 1958, the night of the senior prom, at Springfield high. Go, Chipmunks! Entertainment was supposed to be supplied by the Crooning Crab Cakes, from the boy’s glee club, but their band leader has just been suspended for smoking outside the girls’ locker room. Luckily, the boys are replaced by four singers in crinolines, the Marvelous Wonderettes. What ensues is an utter charm bomb. Set in two acts, first on prom night and then the ten-year reunion’s night, we are treated to a nonstop sock-hop medley of first ’50s and then ’60s rock-and-roll hits. Being performed on the main stage of the Saint Louis Repertory Theater, this musical is the perfect balm for our often raw January weather. We loved it!
