Watch Lady Gaga’s Stunning Performance of ‘Til It Happens To You’ at the Oscars

The track, which was co-written by Diane Warren, is up for Best Original Song

After being introduced by Vice President Joe Biden (who walked onto the Hollywood stage to the tune of the Indiana Jones theme), Lady Gaga performed her Best Original Song-nominated track “Til It Happens To You” from the film The Hunting Ground. After Biden made a fiery plea to the audience to help bring an end to sexual assault, Gaga appeared behind a grand piano. She gave a stirring, emotional performance of the track, which was co-written by Diane Warren and made more powerful when the singer was joined by dozens of sexual assault survivors grasping hands onstage. Watch the moment below.
