Lin-Manuel Miranda and Ben Platt attend March For Our Lives on March 24, 2018 in Washington, DC. 

The charity single for March for Our Lives starts with 61,000 sold. On the Hot 100, it bows at No. 49.

Lin-Manuel Miranda and Ben Platt's "Found/Tonight" debuts at No. 1 on Billboard's Digital Song Sales chart (dated March 31).

Released March 16 on I Know Another One/Atlantic Records, the song starts with 61,000 downloads sold in the week ending March 22, according to Nielsen Music.

It also drew 2.1 million U.S. streams, helping enable its No. 49 debut on the streaming-, airplay- and sales-based Billboard Hot 100.

The track is a mashup of two songs from the artists' respective Tony-Award-winning musicals: Hamilton's "The Story of Tonight" and Dear Evan Hansen's "You Will Be Found." Miranda wrote and starred in Hamilton, while Platt starred in Dear Evan Hansen, whose "Found" was written by Benj Pasek and Justin Paul.

A portion of all proceeds from "Found/Tonight" benefit the March for Our Lives initiative, and Miranda and Platt performed the song at the March for Our Lives rally in Washington, D.C., on Saturday (March 24).

Miranda earns his second Digital Song Sales No. 1, following fellow charity single "Almost Like Praying," featuring Artists for Puerto Rico. Released in response to Hurricane Maria, the track debuted atop the chart dated Oct. 28, 2017 (with 111,000 sold). It also became Miranda's highest-peaking song (of now four) on the Hot 100, debuting at its No. 20 peak that week.

Platt scores his first Digital Song Sales and Hot 100 entry. His sole prior Billboard charted title is also a Dear Evan Hansen composition that garnered a No. 1 rank: "Waving Through a Window," credited to Platt and the Original Broadway Cast of Dear Evan Hansen, hit the top of the Dec. 9-dated Dance Club Songs chart.

All charts will update Tuesday (March 27) on Billboard.com.
