Sequins! Dancing queens! ABBA! Go backstage for 'Mamma Mia!'s' 25th anniversary tour at the Ahmanson

Here we go again: Twenty-five years after "Mamma Mia!" premiered on Broadway, the national tour returns to Los Angeles at the Ahmanson Theatre with show-stopping set pieces and a crew that knows the show inside and out.

The beloved jukebox musical, which chronicles a Greek wedding with three potential fathers of the bride, has taken over the Ahmanson through July 19 as part of its 25th anniversary tour, and audience members should expect a full-on ABBA sing-along dance party.

"People come dressed up," said associate choreographer Janet Rothermel. "There's a lot of boas, and there's a lot of spandex, and platform shoes."

Rothermel is one of many people on the creative team who have worked on the show since its original Broadway run in 2001. Associate director Martha Banta and associate music supervisor David Holcenberg have also seen the musical through its nearly 14-year original Broadway run, national tours and numerous international iterations (Holcenberg was its original music director).

"When we were all back together again in rehearsal, it was an extraordinary feeling," Banta said. "Not with the same cast, but Janet, David and I and others that have done it for years. With everything that's been going on in the world in the last three years, it was just a soothing thing to do."

"We've just been embraced beyond what we were used to, which was pretty great," she added.

Everyone involved in the production echoed a similar sentiment: that the "ultimate feel-good musical" is exactly what audiences want to see during painful or overwhelming times. The show's traveling costume supervisor and associate designer Eva Maciek put it most bluntly: "I love working on it because nobody dies."

Rehearsals for the original Broadway run coincided with the Sept. 11 terrorist attacks, Holcenberg explained, and he was struck by audience members' emotional responses to the first shows.

"I'd have people coming down to the pit after the show with tears streaming down their faces saying, 'Thank you for letting us forget the world for a couple hours and just have joy,'" he said. "Because this show is joy. It's full of joy."

Beyond the absurdly catchy music and the rom-com story, part of the show's joyfulness comes from its colorful costumes and beachy aesthetic. The onstage set is relatively sparse, consisting only of a pair of rotating "taverna" walls, but backstage, hundreds of moving parts, including stage mechanics, hand props and costume changes, propel the story forward and keep the production looking effortlessly glamorous.

The obvious choice for coolest costumes, according to Maciek, are the bejeweled jumpsuits worn by titular mamma Donna Sheridan (played by Jessica Crouch) and her Dynamos, Tanya (Jalynn Steele) and Rosie (Carly Sakolove). Each one has hundreds of glittering silver stars attached.

"I'm glad I'm not the one who had to sew them on originally!" Maciek joked. The costumes all originated in London or New York, but they've been traveling from city to city in storage "gondolas" since the current tour started in 2023, requiring constant repairs and touch-ups from local stitchers.

Thematically, Maciek said, the costumes' evolving colors tell their own story throughout the show.

"When everybody arrives at the island, they're all in beige with a little hint of blue," she explained. More blue gets added by "Voulez Vous," and then they transition into jewel tones. "When you get into the wedding scene, everybody is in pinks, soft reds, oranges and yellows," Maciek said. "So there's a real color story that goes throughout."

Ryan Sander, the show's assistant choreographer, dance captain and current "swing" (an actor covering multiple ensemble roles), has a special relationship to his "Voulez-Vous" costume. He originally wore it as a performer on the national tour more than 20 years ago, and when he was called to come back onstage, he found that it still fit like a glove. The costume, a denim vest and pants set with extremely Y2K lace-up details, is representative of the show's approach to fashion trends.

"There is something timeless about these pieces that's just so interesting," he said. "It is a period piece and we stick to that, but there is something timeless about the costumes."

Besides the costume racks, another crucial backstage element are the vocal booths, where the ensemble contributes to the musical soundscape from behind the curtain.

"One of the main things about the 'ABBA sound' is how they layered the vocals, and we do that all live in our show," Holcenberg said. "The ensemble works really, really hard, because when they're not on stage, they don't get any time off. They're just singing their little faces off."

Even though the show has been running for decades, the creative team said each cast brings a new energy and tone.

"Our new Donna, Jess, brings a real rock chick energy to it," Holcenberg said. "Even though the notes on the page stay the same, the casting and the way they perform it still changes from person to person and night to night."

According to stage manager Andrew Volzer, the most "unique" aspects of the show are its long history with a tight crew and its multigenerational appeal - "Not only from the audience perspective, but also for the people working on the show. People are always coming and going," he said.

"We always say, you never leave the island."
