The Fire Island Pines Arts Project's Labor Day Weekend production of "Nunsense A-Men!" the all-male version of writer, composer and lyricist Dan Goggin's "Nunsense," at Whyte Hall, is purest pleasure: it's consistently funny, musical and polished. And proves that, as the stage-struck Little Sisters of Hoboken sing, "Nunsense Is Habit-Forming" indeed. Opening night, on September 4, the first of five performances, is considered here.

This "Nunsense," conducted by Eric Alsford and directed and choreographed by Casey Colgan, with set design by Glen Wielgus, yields one magical moment after another. Mike Cueto, as Sister Mary Regina, the Mother Superior, and Tom Vaughn as Sister Mary Hubert, the Novice Mistress, vie for power, but admit that they are, after all, "Just a Coupl'a Sisters," harmonizing and hoofing. Sister Hubert and novice Sister Mary Leo-a graceful Rory Hughes-find parallels in their situations-Mary Hubert won't be Mother Superior and Mary Leo won't ever be a famous ballerina, as Mary Regina does not find the tutu an acceptable substitute for the habit-but the Novice Mistress reassures her charge that "The Biggest Ain't the Best."

Daniel McDonald's mischievous, streetwise Sister Mary Robert Anne, the convent's driver, the understudy for the benefit show the sisters are putting on, and the underdog that we root for, touchingly tells us of the frustration of "Playing Second Fiddle" and slyly enlists Rory's Leo for the "Swan Lake"-inspired "Dying Nun Ballet," recounting the woeful story of the botulism in the vichyssoise which killed off 52 of the sisters. Jack Lichtenstein makes a winning cameo appearance as clueless Sister Julia, Child of God, who whipped up the fatal soup.

Steven Alan Black, co-producer of "Nunsense A-Men!" with Michael Savino, has wonderful star turns as dippy Sister Mary Amnesia, a regular Sister Malaprop, who "Could've Gone to Nashville" and become a country singer, but for her memory loss.

Cueto shows us what happens when a nun sniffs an unusual stimulant. Vaughn stops the show with Hubert's 11 o'clock gospel number, "Holier Than Thou." The nuns tap dance to beat the band, when they "Tackle That Temptation with a Time Step," and take an upbeat approach to a run-in with the New Jersey Board of Health, merrily chorusing, "We've Go to Clean out the Freezer."

These Pines nuns take some pertinent liberties with the text, as Robyn Bird and the Meat Rack get mentioned in the rollicking "Baking with the BVM" scene, with Cueto, Vaughn and Black, and the lilacs, which Hughes claims "bring back memories," are ostensibly a gift from B'Nai Olam, the congregation which holds High Holiday services in Whyte Hall later this month.

Remaining performances of "Nunsense A-Men!," are, at this writing, on September 5 and 6, at 6 and 9 pm, and tickets are $50.

On opening night, amiable Dan Goggin took the stage after the performance and, after a presentation to him from the company, spoke and answered questions about "Nunsense" and its sequels and many productions, the stars who have appeared in it, and the nuns who taught him and on whom he lovingly based his characters.
