Downrange began several years ago as a pared down version of the Chorale that could accompany the sergeant major of the Army’s annual tour of deployed troops in Iraq, Afghanistan and Kuwait, which brought USO-sponsored celebrity performers together with Army musicians and vocalists to entertain troops around the Christmas holidays.

The slimmed down group — nine vocalists and a five-piece band — have now shape-shifted the Family-friendly Choraloween into a more adult-themed Deranged.

This doesn’t mean there’s any objectionable material in the concert, emphasizes show director, choreographer and performer Staff Sgt. Juan Rodriguez, it’s just that the lighting, smoke machine, straightjacket costumes, vintage black-and-white clips from ‘‘Frankenstein” and other horror films might be too intense for younger audiences.

One of the reasons the show-choir Chorale morphed into Downrange, which plays largely rock-n-roll, country and pop, is to better appeal to young adults who might be considering the Army as a career. It serves as a recruiting tool and shows the Army can be hip, Rodriguez said.

The idea for bringing the show out of mothballs and revamping it began, in part, after the Military District of Washington deputy commander told the Army Band commander how the show was one of the first things that made him smile as a Soldier after the horrific events of 9⁄11, explained Lt. Col. Andrew Esch, Army Band deputy commander and officer-in-charge of Downrange. That got the ball rolling to reviving it, he said.

Deranged, which has its final show today at 7:30 p.m. in Brucker Hall, is filled with new and old songs tied to the haunted season. Michael Jackson’s ‘‘Thriller” has been in Downrange’s repertoire for awhile and is a carryover from Choraloween. ‘‘Time Warp,” from the ‘‘Rocky Horror Picture Show” and the Eagles ‘‘Witchy Woman” are staples of other Downrange shows, while Rihanna’s ‘‘Disturbia” and Bushwalla’s ‘‘[It’s Hard to Be a] Gangster [With a Basket On Your Bike]” are new for the group.

The program also includes such contemporary classics as The Rolling Stones’ ‘‘Sympathy for the Devil,” Bon Jovi’s ‘‘Wanted: Dead or Alive,” the Dixie Chicks’ ‘‘Earl Had to Die,” and Patti LaBelle’s ‘‘Lady Marmalade,” among other highlights. Elton John’s ‘‘Funeral for a Friend” is performed as an instrumental to showcase the Downrange band, a unit that is occasionally supplemented in Deranged by a string quartet and horn section on loan from other Army Band units.

In addition to dancing and singing, many of the performers in Deranged have secondary behind-the-scenes roles. Staff Sgt. Martha Krabill choreographed the movement to ‘‘Disturbia,” which also incorporates a dozen young dancers from a studio where she teaches. Sgt. 1st Class Christal Rheams is responsible for getting ‘‘Deranged” filmed for broadcast to troops on Soldiers Radio and Television and a soon-to-be-available Web cast. Master Sgt. Beverley Benda, who is involved with the local theater scene, is in charge of props and costumes.

There’s a little something for everyone in Deranged. ‘‘Time Warp,” has some tasty tap dancing by Krabill. Master Sgt. Caleb Green invests squinty-eyed cowboy pathos and his soulful voice in ‘‘Wanted: Dead or Alive.” The long-limbed Staff Sgt. Miles Simmons deflates his song’s ‘‘Gangster”-manquÈ by riding a lavender training-wheeled kids bicycle on stage — a comic visualization the rap song only hints at.

Sgt. Maj. Mercy Diez seems to channel a little of the late Eartha Kitt in her lead vocals and cackling on ‘‘Sympathy for the Devil.” She’s nearly obscured by a red, hooded, wraparound cape when she first appears on stage. After doffing the cloak, a head with horns is revealed. The vocalist also makes the most of the instrumental portion of the song by using her satanic scepter as if it were a martial arts baton and retrieving her previously discarded cape to twirl it as if she were a Chinese ribbon dancer or a matador from Hades.

The content of the show is a collective effort, said Rheams, explaining that everyone in Downrange brought ideas to the program, trying out and discarding possible selections.

Most of the songs come from the Downrange book — songs the group already has permission to perform and have written arrangements by Army Band personnel, Rodriguez said. ‘‘All the songs are pretty true to the originals.”

‘‘The show’s title was Christal’s idea,” he added.
