A special edition of Kanye West’s Sunday Service series took place in Dayton, Ohio this weekend.

The performance wasn’t announced until the morning of, according to People. Kim Kardashian shared the event on Twitter, writing that it happened “in support of the victims and survivors of the Dayton mass shooting.” Kim attended the event, as did North and Saint. Also in attendance were some of those who were impacted by the shooting. The performance was livestreamed, which you can rewatch here.

Dave Chappelle also appeared and thanked Kanye for showing up. “Dayton, today the whole world is looking at you,” Chappelle said, adding that while the town had “been through a tough time,” they were still standing.

“We’re still strong and the only way—the best way, that we can honor our fallen is by getting up better than we were before,” he continued. “We will not let those people die in vain.”

He added, “Thank you very much Kanye for coming out here, man.”

Chappelle will host a block party and benefit concert in Dayton from 4 p.m. to 10 p.m. on Sunday. 

The mass shooting in Dayton left nine people dead and 27 injured in early August. The incident followed a mass shooting in El Paso, Texas, where 20 people were killed and 26 were injured inside a Walmart.
