The fourth annual Ally Coalition Talent Show hit Town Hall in New York City Wednesday night, bringing with it a slew of (thankfully YouTubed) moments of sonic euphoria. Lorde joined Ally Coalition co-founder Jack Antonoff for renditions of the Carly Rae Jepsen instaclassic "Run Away With Me" and Roy Orbison's 1989 Mystery Girl hit "You Got It."

Elsewhere, Lorde performed her lead Melodrama single "Green Light" and Antonoff paid tribute to the late Dolores O'Riordan with a Bleachers cover of The Cranberries' "Dreams." Kacey Musgraves, Spoon, Shamir, and more also performed.

The charity-focused evening, unfortunately, was briefly dampened by a rude-as-fuck heckler. After Lorde thanked the crowd for being "so nice," Variety reported, a man shouted out something about Israel also being nice as an apparent response to Lorde's recent decision to cancel a Tel Aviv show.

Antonoff promptly responded:

Oh, come on. No, hold on. We're here raising a shit ton of money. Fuck that negativity . . . You know where they're nice is right here, alright? Right fucking here. That motherfucker better donate a couple, ten thousand dollars more to this shit.

The reason for Wednesday's night performances—the non-profit Ally Coalition—was started by Jack and his sister Rachel to "take action for LGBTQ equality" via special events, tours, and campaigns. Find out more here.

Lorde's sophomore album Melodrama—on which she collaborated with Antonoff—is up for Album of the Year at this Sunday's Grammy awards. "It's crazy I'm the only woman in my category, and I feel very proud of that," Lorde told Billboard of the nomination. "I'm wearing that mantle for sure. But I'm also stoked that I'm in there with four incredible artists of color—it's a big moment for the Grammys. It's exciting when these institutions move in the right way. To me, that is a huge victory."
