Bayer wanted to do something different for its Las Vegas convention, so they kicked off the event with a rousing performance by the Desert Angels.

Performing to the theme “Make it Happen,” the choir adapted the popular song by Mariah Carey and brought the house down.

When the choir returned to close the meeting, not a person was seated as the audience sang, clapped , and shouted along.

Three standing ovations later, the Desert Angels were proud to have pulled off yet another successful event.
