Bex Johnson led the ensemble cast as Mother Superior Sister Mary Regina, a former circus performer who yearns for the spotlight.
Johnson delivered a near flawless performance, lending her rich contralto and skill with a feather fan to her solo numbers - and providing uproarious physical comedy in a scene where her character discovers some "sinful" temptations.
Susanne Richardson kept the caustic one-liners coming as Mother Superior's second-in-command Sister Mary Hubert, and gave a formidable rendition of a gospel tune in the finale, reminiscent of Whoopi Goldberg in Sister Act.
Siobhan Connor, with her exquisite tones and pink ballet slippers under her habit, was the vocal rock of the show as Sister Mary Leo, the endearing novice with dreams of being "the first nun ballerina".
Providing the swagger was Courtnay Fafeita as the "streetwise nun" Sister Robert Anne, who is initially shunted into an understudy role.
While she didn't have the strongest voice - though her "sleazy club number" was fabulous - her "shimmies" and facial expressions charmed the pants off the crowd.
The undisputed show-stealer was Bridget Connor as Sister Mary Amnesia, who has lost her memory after a crucifix (of course) fell on her head.
I later learned that Connor had a severe case of laryngitis - but she nonetheless sparkled, with her adorable lispy Brooklyn accent, doddery mannerisms and comically clumsy dance moves.
I found the story to be a bit frivolous. But there are plenty of great, catchy tunes about leper colonies, doing ballet warm-ups during prayer, avoiding temptation and achieving sainthood. And the dance routines - ballet, tap, burlesque, jazz, and something resembling Carmen Miranda - are delightful.
