Broadway stars Lin-Manuel Miranda and Ben Platt plan to donate a portion of the proceeds from their new mashup song to the anti-gun violence march on Saturday.

The song, called "Found/Tonight," is a mashup of music from "Hamilton" and "Dear Evan Hansen."

Honored to team up with @Lin_Manuel on “Found/Tonight,” a gorgeous mashup of @HamiltonMusical and @DearEvanHansen arranged by the great @LacketyLac. Proceeds go to the incredible #MarchForOurLives Initiative, so stream & download & listen! #GunControlNow https://t.co/WrWiwer6YX — Ben Platt (@BenSPLATT) March 19, 2018

Portions of the proceeds will go to the "March for Our Lives," the march being held in Washington, D.C., to protest gun violence and demand lawmakers take action to prevent it.

A student from Marjory Stoneman Douglas High School in Parkland, Fla. — where a gunman killed 17 people last month — promoted the song on Twitter, encouraging people to listen to it.

@BenSPLATT and @Lin_Manuel did something amazing. You should go listen to it.



Found/Tonight. Download it. Portion of the proceeds going to our movement.



This song takes the two songs I listen to most for inspiration and puts them in one nice convenient spot.

Students have been leading the charge on gun control since the Florida shooting.

Students who survived the shooting have been rallying lawmakers and demanding new gun laws to keep their schools safe.

Last week, students across the country took part in a nationwide school walkout, with many holding 17 minutes of silence to remember the 17 people who died in the Florida shooting.
