Miss Manners dictates that in social settings one should not bring up religion. But can I just say that when I was a shy child of six, seeing a Catholic nun in full habit scared the bejeezus out of me? Nuns were mysterious. You never saw them eat or drink or sweat. Never did I see a nun dance. And they were always worried about the soul. But the nuns in the Circa ’21 Dinner Playhouse’s musical comedy Sister Act know soul – as in soul music, sung with such energy that it had me clapping and swaying in my seat. And could those nuns dance! This joyful musical based on the 1992 film was a crowd-pleaser on opening night, and I predict the same for future performances.
