Demi Lovato and Nick Jonas paid tribute to the victims of the Orlando nightclub shooting at a concert in the Florida city on Saturday night. They were joined by Andra Day onstage at the Amway Center, and performed the song "Rise Up," a single from Day's 2015 album Cheers to the Fall

The trio shared separate verses of the song, stirring emotions as the names and ages of all 49 victims were displayed on a screen in the background. Watch fan-shot video of the performance above. 

Before the performance, a local man named Hank said a few solemn words of remembrance, while Lovato and Jonas stood nearby. Here's part of his speech, per Rolling Stone: 

"Orlando, you've been through a lot. In the last month, you've had two shootings, one of which was the most deadly shooting in all of America's history...so we want to pause in the midst of this exciting night… we can to pause and say a prayer, a prayer of healing."

Two days before Jonas and Lovato's Future Now tour stopped in Orlando, Justin Bieber was in the city. The singer also memorialized the victims in a similar fashion, while playing a stripped down version of his song "Purpose."
