WATCH: Big & Rich Perform "God Bless America" At Route 91 Harvest Festival

While there's no doubt that the events that unfolded Sunday evening at the Route 91 Harvest Festival were horrific, there are moments of true love, compassion, and unity that need to be remembered and celebrated.

Sunday evening at the Route 91 Harvest Festival, Big & Rich took the main stage about 2 hours before a lone gunman opened fire on the crowd of at least 22,000 attendees.  As a tradition during their concerts, the duo brought members of the military on stage to lead a sing a long of "God Bless America" with the crowd who held up their cell phones, creating a sea of lights that can be seen in the video.

As Big & Rich puts it, the emotional video is an example of American unity.
