Watch This: Pulse Tribute by Nick Jonas, Andra Day and Demi Lovato

During the Orlando concert stop of the Nick Jonas and Demi Lovato tour at Amway Center, the singers were joined onstage by singer Andra Day for a spiritual tribute to those lost in the Pulse tragedy. As the singers sang, the names of all 49 victims scrolled on a large screen behind them. The final name was a surprise: singer Christina Grimme, the performer shot during a meet and greet just after her concert ended at The Plaza Live.
