As most of the Bonnaroo grounds woke up to the horrifying news of the deadliest U.S. mass shooting at an LGBT club in Orlando on Saturday night, several performers sprung into action on Sunday, honoring the victims of the massacre and calling for action throughout the day and evening.

The Dead & Co.’s Bob Weir ended the evening with an impassioned speech against the homophobic politicians preaching "hatred and intolerance" while feigning sympathy for the gay victims of the shooting. "Register and vote,” Weir declared. “Get those assholes out of there.”

Earlier, Third Eye Blind’s Stephan Jenkins introduced “Jumper” with the line, “Sing this for everyone in Orlando tonight.” During the finale of “Semi-Charmed Life,” a visibly moved Jenkins announced to the overwhelming evening crowd, “We are all one! We must be together on this! We are all one!”

Langhorne Slim shouted out Orlando during the Bluegrass Superjam, as did X Ambassadors on Twitter hours before their set. Jason Isbell delivered one of the more heartwarming speeches on Sunday afternoon (via The Tennesseean):

"It's a happy day on stage, but it's not a happy day everywhere in the world right now. The only thing I know to say to you is have faith. … I think we're all good people out here. I think we've got the brains and the heart that it takes to figure it out, to put a stop to this kind of (expletive) and learn to live peacefully together. But the trick is compassion and empathy. ... That's the only thing that I've learned.”

In the Comedy Tent, stand-up artists weaved around insensitive jokes and got serious about the Orlando situation. “We just shouldn’t be shooting people!” comedian Alice Wetterlund suggested during an early afternoon set, while John Early started his set by revealing that he wore his most flamboyant shirt that day in solidarity with his gay brothers and sisters.

And of course, there were tributes to Orlando offered by festival goers on Sunday:
