Broadway’s Elphaba from ‘Wicked’ sang the national anthem at Eagles NFC Championship Game

Broadway’s current Elphaba swapped out her Wicked green makeup for some midnight green fan gear Sunday.

Mary Kate “MK” Morrissey — a household name for musical theater fans who gained fandom for her primary role in Wicked and her social media presence — performed the national anthem at the Linc ahead of the NFC Championship Game.

It was a full circle moment for Morrissey, who grew up in a big Irish Catholic family in Downingtown, attending Bishop Shanahan High School, and participating in the Philadelphia All Catholic Chorus.

“My two grandparents are off the boat from Ireland and landed in Philly,” Morrissey told The Inquirer from her car ride home after two performances Saturday. “My pop used to sing to the Irish radio and work the night shift at the Acme. They had seven kids in South Philly. My mom’s parents too were in South Philly and then everybody sort of moved to Delco.”

She’s also a die-hard Eagles fan — enough so that she was willing to miss two scheduled Wicked performances on Sunday to attend the game instead, a serious sacrifice since her yearlong contract with the production comes to a close on March 2.

“I will be out of both shows on Sunday because I will be singing the national anthem at the championship game for the birds, baby,” Morrissey posted to her Instagram story on Friday, sitting in her Broadway dressing room and wearing an Eagles beanie. “Go Birds.”

The actor said she grew up in an Eagles household stuffed with memorabilia.

“The game was always on,” she said. “I think I was born knowing the Eagles’ fight song. I can’t even remember learning it. That’s how long ago I learned it.”

When asked about her favorite Birds memory, Morrissey said she was performing the Mean Girls Broadway show in Philly when her dad got the entire audience to sing the fight song and do the Eagles chant before the show started.

On her TikTok and Instagram accounts, which each have over 100,000 followers, Morrissey joked about an alternate ending to the national anthem where she morphs the final note into Elphaba’s signature battle cry from the end of “Defying Gravity.”

The song’s riff was originally made famous by the inaugural Elphaba, Idina Menzel, on Broadway in 2003, and recently by Cynthia Erivo, who plays the protagonist in the Oscar-nominated film adaption, which premiered in November. Traditionally, each performer who plays Elphaba puts their own spin on it.

The question going into Sunday was would Morrissey actually tack it onto the end of “The Star-Spangled Banner?”

The singer had said her Eagles broadcasting contact suggested she keep things traditional. Meanwhile, the Eagles’ TikTok account weighed in pushing for the war cry.

“But I think I’m just gonna do the standard one because I feel really proud that they asked me and [that] I’m Philadelphia’s own Mary Kate Morrissey,” she said. “I’m there to make Philly proud more than I am to make Wicked people proud — even though it would be kind of funny.”

She indeed played it straight.

At the tail end of her year as Wicked’s principal role, Morrissey says she’s taking it all in.

“My [costar] Galinda tonight was like, ‘how cool that at the end of this big contract, you also get this other fun thing to celebrate and go out on with a bang?’” Morrissey said. “I feel like I’m rich in opportunity right now and I’m super grateful and really excited for whatever comes next.”

And both Wicked and Philly’s current focus on green isn’t lost on her.

“I think it’s really apropos that Philly was just nicknamed the Emerald City and that I get to go have one short day in the Emerald City,” Morrissey said. “I’m really looking forward to it ... go Birds.”
