Adele’s 2016 world tour has given us several memorable moments thus far, including the time she photobombed a fan, the time she let two guys sing with her onstage, and the time she helped a couple get engaged. But her tribute performance in the wake of Tuesday’s terrorist attacks in Brussels easily stands out as the tour’s most touching moment to date.

Just hours after the bombings in Belgium’s capital city left dozens dead and hundreds injured, Adele took the stage for the final night of her six-show residency at London’s O2 Arena. In a fan-shot video, she can be heard asking the audience to illuminate the venue with their cell phone lights.

“This is ‘Make You Feel My Love,’ and this Is for Brussels tonight,” she said before launching into the Bob Dylan-written ballad. “I want you to all sing it with me, all right, so they hear us.”

After the performance, Adele told the roaring crowd, “I don't think I've ever actually been so moved before in my life at one of my shows, that was just so beautiful. Thank you very much for doing that... I think they heard us.”
