“;A Chorus Line”; has been staged here so often that each new production is akin to a class reunion. This time the “;reunion”; is at Army Community Theatre, and all of our old friends are in great shape.

Chris Villasenor (Paul San Marco) nails his big scene as the young man who breaks down in tears recalling the first time his father acknowledged him as his son. Renee Garcia Hartenstein (Diana Morales) leads the cast in a stirring rendition of “;What I Did for Love”; and brings humor and irony alike to “;Nothing.”; Robyn Gee-Franklin (Kristen Urich DeLuca) gets well-timed comic support from Leonard Villanueva (Al DeLuca) while she sings perfectly off-key in “;Sing!”;

Dwayne Sakaguchi (Mike Costa) personifies pizazz as the powerhouse tap dancer in “;I Can Do That.”;

There are memorable performances in slightly smaller roles. Nic Amari (Don Kerr), for example, as the guy who lucked into the opportunity to pal around with a big-time stripper while he was still in high school. Philip Amer Kelley (Mark Anthony) as the guy who learned about sex from one of his father's medical books only to misdiagnose his first wet dream as symptoms of gonorrhea.

ACT director Vanita Rae Smith and choreographer Grace Bell share credit for a job well done with the iconic song-and-dance numbers. From the frenetic energy of “;I Hope I Get It”; through the expansive catharsis of “;What I Did for Love,”; the ensemble performs with excellent effect. The interplay between different voices — all those ironic observations and one-liners — works almost without fail.

The problems are in the sound and lighting. Peter Togawa (Zach) was hobbled on opening night by a microphone that made him sound hollow even when he was onstage with Villasenor or Autumn Ogawa (Cassie) — both of whom sounded normal. The orchestra overwhelmed the actors' voices several times; Jody Bill's (Val Clark) first plaintive lament about the delayed onset of her physical development was almost lost in the audio mix, but her big number, “;Dance: Ten; Looks: Three,”; was the acid-etched highlight it should be.

Lighting was one of the problems with Ogawa's surprisingly passionless solo number, “;The Music and the Mirrors.”; For far too much of it she was dancing in shadows.
