A group of Broadway stars sang "What the World Needs Now" at the Democratic National Convention on Wednesday. The performance was a tribute to the victims of the Orlando mass shooting, which left 49 dead at gay nightclub Pulse in June.

Performers included actress Kristin Bell, Darren Criss, Tony winners Audra McDonald, Brian Stokes Mitchell, Idina Menzel, Ben Vereen and Debra Messing.
