Lin-Manuel Miranda and Ben Platt came together for a new song "Found/Tonight" in support of the March For Our Lives following the deadly shooting at Parkland, Fla.'s Marjory Stoneman Douglas High School where 17 people were killed. Both stars tweeted about the mashup and shared their thoughts on gun violence. The proceeds from the song will go toward the March Of Our Lives, set to take place this weekend. Proceeds go to the incredible #MarchForOurLives Initiative, so stream & download & listen!
