The performance began with a rollicking “80s Night” medley, consisting of snippets of its “title song,” NYCGMC’s version of “Ladies’ Night,” Suzanne Vega’s “My Name Is Luka,” and, among other songs, “1999,” “Automatic,” “She Drives Me Crazy,” “Too Shy,” “I Still Haven’t Found What I’m Looking For,” “Where the Streets Have No Name,” “Sunday Bloody Sunday,” and “Rock Me Amadeus.”

Among the highlights of an “80s Movie Medley” were an upbeat title number from “9 to 5,” Dolly Parton’s song; sentimental renditions of Larry Hensley and Jeff Silbar’s “Wind Beneath My Wings,” sung by Bette Midler in Garry Marshall’s film “Beaches,” and “Somewhere Out There,” from “An American Tale;” and an exultant “I Sing the Body Electric,” to Walt Whitman’s words, from the movie “Fame.” Admirable soloists were Stephen Bennett Milbauer, Gary Wayne Farris, Edwin Yangga and Sonelius Kendrick-Smith.

Choristers began a 17-song Madonna tribute by standing reverently and launching into “Like a Prayer,” “Like a Virgin” and “Papa, Don’t Preach,” following these with “Material Girl,” “Borderline,” “Express Yourself,” “La Isla Bonita,” “Crazy for You,” and “Cherish.”

Two ensembles within the chorus took center stage during the performance. The Ambassador Chorus, the chamber choir, directed by Casey J. Hayes, lent hushed, dulcet tone to Journey’s “Open Arms,” by Steve Perry and Jonathan Cain. Uptown Express, the pops group, under Followell, began with a heartfelt “Streets of Philadelphia,” by Springsteen, which brought back memories of Tom Hanks, as a gay lawyer (and opera queen) with AIDS in Jonathan Demme’s film, “Philadelphia,” for which it served as theme song, and continued with a wistful pairing of Lauper, Bob Hyman and Jules Shear’s “Time After Time” and “All Though the Night.” Ryan Leeds, John DePalma, Alex Goro and Kendrick-Smith were soloists.

Disco balls, strobe lights, smoke, and a quartet of sensual flag dancers provided atmosphere for a rousing “80s Club Mix,” which included the Pet Shop Boys’ “Left to My Own Devices,” Rick Astley’s “Together Forever,” the late Laura Brannigan’s “Gloria,” Chaka Kahn’s “I Feel for You” and Shannon’s “Let the Music Play.” Scott Piro was a soloist.

Chorus members donned their best disco duds for a “Girls Just Want to Have Fun” medley, which featured a bevy of drag beauties, including Curtis “Dakota Sue” Knecht, the reigning Miss Fire Island, in chic workout attire, channeling Olivia Newton-John and singing “Let’s Get Physical,” and John “Jacqueline Jonée” Nieman, elegant in blue, clutching a cocktail glass, and “doing” Joan Collins, engaging in a hair (or wig) pulling scene with a “Dynasty” co-star. Some of the songs here were Pat Benatar’s “Love is a Battlefield,” Whitney Houston’s “I Want to Dance with Somebody,” the Bangles’ “Manic Monday,” the Go-Gos’ “Our Lips Are Sealed,” the Pointer Sisters’ “Jump,” and Toni Basil’s “Mickey,” for which all singers on stage broke out pompoms and turned cheerleader. Ryan Stem, Jeff Lettiere, Fredy Harris, Rob Cordell and Christopher Manna sang other solos. A gently rocking “Purple Rain,” the song by Prince, followed.

A fascinating, silver clad androgynous figure and NYCGMC’s answer to Boy George were among the participants in “Gender-Bender,” in which the Eurythmics’ “Sweet Dreams” and “Would I Lie to You,” Boy George’s “Karma Chameleon, the Thompson Twins’ “Hold Me Now,” Soft Sell’s “Tainted Love,” and Adam Ant’s “Goody Two Shoes” were selections. Michael Osso, Vincent Lacy, JT Taylor, and Lettiere had solo turns. Kip Bonsignore, Rick Aronstein and Matt Leahy were featured in “I Want My MTV”, which included the eponymous Dire Straits number, the Police’s “King of Pain,” “Video Killed the Radio Star,” “Heat of the Moment,” and “99 Red Balloons.”

The choristers’ grand finale had dancers in ghoulish garb and makeup, spilling out into the audience, for the Michael Jackson-Vincent Prince collaboration “Thriller,” written by Rod Temperton, in which Christopher Wagley and Richard Raymond Donahue were strong soloists.

On June 17 and 18, NYCGMC returns to the Skirball Center for its GLBT Pride concerts, entitled “Season of Pride,” including an appearance by its Youth Pride Chorus.
