Fan-captured-footage shows the band performing 'Animal', before Vedder stops the band mid-song.
Apparently a woman in the crowd had started hitting another fan because he was annoying her while filming the show.
Vedder asks for the house lights to turn on, and says to the violent fan:
"Hey, hey, hey, hey, hey – I saw the whole thing, I know, it was annoying you. You were bummed out 'cause he was filming the whole time. Has it been the whole show or just now? Just now when I came over? Was it the whole time?"
"The thing is, I know it upset you, but you can't fuckin' hit him in the back of head either, even though you're a woman. I appreciate the fact that you can be strong.
"Quit hitting him — you're out of here. Violence is not allowed. I'm sorry ma'am, there's no violence allowed. You could've waved to me, I was lookin' right at you.
"Sorry about that, it's just not cool, we're not hittin' people here. Sorry."
It then appears that security takes care of the situation.
Vedder then instructs the band "chorus", counts them in, and the band rip straight back into it.
Vedder is no stranger to kicking out rowdy fans at Pearl Jam gigs. Back in 2016, he did the exact same thing when a fan was annoying another fan by waving his finger in her face.
One YouTube comment says,
"I’ve never seen a lead singer so acutely aware of EVERYTHING that is going on in the audience! It’s incredible. And he’s always watching out and for people and definitely not afraid to call them out. Just like he did here. He’s awesome man. Love that guy so much."
