13 Concert and Nightclub Tragedies Before Route 91 Harvest Festival

"Emotional. Chilling. Unexpected."

Jason Aldean paid tribute to the victims of the Las Vegas shooting with a rendition of Tom Petty's "I Won't Back Down" during a cold open on "Saturday Night Live."

Aldean was headlining last Sunday at the Route 91 Harvest Festival in Las Vegas when a man killed 59 people and injured at least 527 in what has become the deadliest shooting in modern U.S. The bullets rained down on the 22,000-person crowd of while Aldean was performing on stage.

"I'm Jason Aldean," the singer said to the audience. "This week, we witnessed one of the worst tragedies in American history. Like everyone, I'm struggling to understand what happened that night and how to pick up the pieces and start to heal."

"So many people are hurting," he continued. "There are children, parents, brothers, sisters, friends -- they're all part of our family. So I want to say to them: We hurt for you, and we hurt with you, but you can be sure that we're gonna walk through these tough times together every step of the way because when America is at its best, our bond and our spirit -- it's unbreakable."

The country singer's performance of "I Won't Back Down" was also a tribute to Petty -- an American rock legend -- who died unexpectedly only one day after the Las Vegas shooting. He was 66.

Aldean's "SNL" dual-tribute was his first live performance since the tragedy. See how viewers responded in the tweets below.
