Ringling Bros. may have retired its elephants, but the pink, plumey costumes worn by the women in the circus’s pachyderm parade will live on in Signature Theatre’s “La Cage aux Folles.”

Will it be the greatest show on Earth? Maybe, maybe not. But some Signature staffers are calling “La Cage” the biggest show they’ve ever done, at least when it comes to props and costumes. And that’s where the elephant-parade hats, headdresses and bustles come in, courtesy of Bonnie Feld, the chairwoman of Signature’s board and wife of Kenneth Feld of Feld Entertainment, which produces the circus and “Disney on Ice,” among other traveling shows.

When Bonnie Feld heard that Signature was going to stage “La Cage,” which is set in a 1970s Saint-Tropez nightclub, she suggested checking out the circus’s costume inventory.

The lead characters in the show are drag impresarios who try to play it straight after their son proposes to a young well-to-do woman. (The 1996 Mike Nichols film “The Birdcage” is derived from the same 1973 French play.) In Signature’s staging of the 1983 musical, a rotating set will alternate between dainty living room scenes and the Riviera club, which will feature costumes the circus performers wore in the early 1980s.

Signature costume designer Frank Labovitz and director Matthew Gardiner sent sketches to Ringling in Florida, where inventory staffers went to work, emailing photos of various sequined accoutrements to the theater.

“I would have loved to run amok in that warehouse,” Labovitz said. The 500,000-square-foot building is the third largest in Florida, according to Ringling, and 40,000 square feet are devoted just to costumes. (Only a NASA assembly building and a new Amazon facility are larger, the circus says.)

Once the items that Signature had chosen arrived at the Shirlington theater, a mild tussle over feather bustles ensued. The job of props master Becca Dieffenbach includes setting up the drag queens’ dressing rooms, which will be visible to the audience on both sides of a thrust stage. (Lee Savage designed the sets.) Dieffenbach had planned to use a flowing pink-and-green bustle as decoration, but Labovitz noticed that the feathers matched the silver sequined headpieces with fuchsia plumes that he had already received.

The circus ended up sending seven more of the bustles to outfit each “Cagelle” — as the chorus “girls” are known. In the show’s finale, the Cagelles will wear an ostrich feather bustle and matching hat that would have cost Signature a small fortune to make.

Other circus-performer wear that Signature borrowed includes flowing robes edged with feathers, hats too extravagant for the Kentucky Derby, and a peacock-like tail that Dieffenbach calls “a feather backpack collared thing.” Whatever it is, her assistant promptly unpacked it, strapped it on and paraded around the prop shop.

“This stuff is nicer than anything that we could have ever afforded,” Dieffenbach said. “It will really make an impact and say something about the club we are creating onstage. It’s extravagant and over the top. We have so many sequins and feathers. It’s a look that works.”

American Pops season

At Monday night’s Helen Hayes Awards, conductor Luke Frazier had the unfortunate task of playing off winners whose acceptance speeches exceeded 45 seconds. It was a thankless job, but Frazier was happy to have his ensemble, the American Pops Orchestra, onstage at the Lincoln Theatre. Later in the week, he was also happy to announce the group’s second season of bringing Broadway performers and local musical theater stars — including several 2015 Helen Hayes nominees — to the concert stage.

“I wanted to bring back some favorites,” Frazier said in an interview.

The American Pops’ second season opens Nov. 11 at Lisner Auditorium with “I’ll Be Seeing You,” Frazier’s original revue of songs from the 1940s. Performances by Ron Raines, Florence Lacey and Claybourne Elder — all New York-based actors who have performed at Signature Theatre — will be interspersed with readings from letters that Frazier’s grandparents wrote to each other during World War II.

“I am all about creating original shows just for our orchestra,” he said.

On tap in January next year: a showtune party celebrating Barbra Streisand’s 75th birthday, with performances by Tony nominee Laura Osnes (“Cinderella,” “Bonnie and Clyde”) and Amber Iman, who is now in “Shuffle Along” on Broadway and who received a Helen Hayes nomination this year for her role in Shakespeare Theatre Company’s “Man of La Mancha.”

The Pops’ second season continues in March with a concert reuniting Austin Colby and MaryJoanna Grisso, who played Tony and Maria in Signature Theatre’s recent “West Side Story,” in a new staged production of “Cinderella.” The season ends April 7 with two locally based performers, Warren Freeman and Bayla Whitten, performing songs from the 1980s with a DJ and the 35-member orchestra.

Solas Nua extension

The Irish cultural organization Solas Nua is back on the Washington theater scene after a nearly five-year absence. The troupe’s phoenix-like show is “Wild Sky,” Deirdre Kinahan’s historical drama about a rebellious young Irish couple, which Solas Nua has been staging in two D.C. homes. The script features two characters, but director Rex Daugherty added an ensemble to dance, sing and bang the bohdran. Post critic Peter Marks praised “Wild Sky” for its inventive staging and Kinahan’s “cascade of lyrical narratives.”

The show sold out, but rather than overstay its welcome in private homes, Solas Nua has arranged an extension from June 1 to 4 in a slightly larger but still intimate venue — the Friends Meeting House on Florida Avenue NW. Before each show, audience members are invited to stroll in the garden, where performers will offer soda bread, Gaelic language lessons and a chance to try out dance steps.

Should the extension be successful, Daugherty said, “Solas Nua will definitely be back.”
