Lin-Manuel Miranda and Ben Platt release a special song for 'March for Our Lives'

On March 24, people across the country will march in the streets to demand an end to mass shootings—and now, they have a soundtrack.

Broadway heavyweights Lin-Manuel Miranda and Ben Platt have joined forces Monday to release "Found/Tonight," with all proceeds going towards March for Our Lives initiative.

"Found/Tonight," arranged by the legendary Alex Lacamoire, is a mashup of Hamilton's "The Story of Tonight" and Dear Evan Hansen's "You Will Be Found." It's streaming on all platforms today.

"When @Lin_Manuel and @BenSPLATT came over my apt to rehearse #FoundTonight, I got goose bumps the minute they started singing each other’s songs," Lacamoire explained on Twitter. "I would tear up in the studio as I listened to the mix, thinking of the kids we made this for."

"Sending a salute to the @AMarch4OurLives initiative. Keep doing what you’re doing — you will change the world," Lacamoire continued.

The music video released of the song also doubles as a fascinating look behind the scenes on the mashup getting recorded.

You can download the sheet music to the incredible arrangement here, and in the words of Miranda: "Go make more music. Tomorrow there'll be more of us."
