It's bound to get a little rowdy at any Pearl Jam concert. But the group won't tolerate actual violence in the crowd — as one fan found out firsthand while being ejected from their Aug. 22 stop in Chicago.

As captured in the fan-shot video embedded above, the band were in the midst of performing the No Code track "Lukin" when frontman Eddie Vedder brought the song to a halt so he could admonish a man he spotted in an angry confrontation with a woman toward the front of the crowd. "Stop, stop, stop, stop," Vedder told the band, pointing at the pair to get the man's attention. "Hey! Hey, mister!"

After the conflict didn't come to an immediate halt, Vedder stepped up his efforts. "Hey, hey, get your finger out of that woman’s face, motherf...," he continued. After the fight was apparently defused with what appear to be security workers pulling the man away, he added, "Clear out ... hey, mister ― all the the fingers are pointing at you."

With the violence averted, Vedder checked in on the woman he'd seen being harassed and complimented her companion for standing up for her when it looked like things were in danger of getting out of hand. "Ma’am, you’re OK? Yeah? You’re good?" he asked. "That’s a good man, taking care of your woman — and then she was taking care of herself, too, pretty good."

Things got back on track after the ejection, with the group resuming "Lukin" and Vedder later joking that the departed concertgoer reminded him of infamous Cubs fan Steve Bartman before adding, "No, that guy was worse. I send my love to Steve Bartman."
