The most telling moment in the Circa '21 Dinner Playhouse's splendid re-imagining of Grease is a minor one, and - like most of this production's finest moments - nowhere to be found in the original script. (It's actually an invention of director/choreographer Ann Nieman's, designed to cover a scene change.) Danny (Jeremy Jonet) and Cha-Cha (Nicole Polzella) have just won Rydell High's dance competition, yet instead of relishing the victory, Danny runs off to re-claim the heart of his true love, Sandy (Cheryl Hoffman). As the decorations come down and the stragglers depart, Cha-Cha - who has even been rebuffed by the nerdy Eugene (Mark D. Lingenfelter) - finds herself alone, and she takes a beat, gazes at the suddenly meaningless trophy in her hands, and quietly, sadly walks off stage.
