Been caught sparring: A concert by the reunited Jane’s Addiction in Boston came to a sudden end Friday night when a clearly enraged Perry Farrell threw a punch at guitarist Dave Navarro — and was restrained by crew members, still appearing physically agitated as he was hustled offstage.

Multiple audience members shared their dramatic video of the altercation after the gig ended in calamity. This emotional explosion — coming on the heels of some “off” moments in other cities that have already been a subject of discussion in reviews and on social media — has some fans waiting to see whether the remaining gigs on the band’s long-awaited reunion tour, their first in 14 years, will proceed as scheduled.

Footage shared on the web shows the band deep into playing “Ocean Size,” the 11th number in a set that usually stretches out to 14 or 15 songs, when trouble erupts between the two most famous members of the veteran band. Some fans reported on social media that tension looked to have been brewing for several songs before it got to the point of fisticuffs.

Video of the lead-up to the scuffle shows Ferrell fiercely grunting in the direction of the audience, before he turns to his right and begins issuing those bellows at Navarro, face to face. He appears to aggressively bump shoulders with the guitarist during a solo, and Navarro eventually stops playing and puts a hand up to Farrell’s chest to establish distance. Then the singer appears to deliver a punch. At that point, as the stage lights are lowered, three men, including bassist Eric Avery, surround and grab hold of Farrell, who is finally forced offstage, still apparently struggling as he’s hustled into the wings.

Once Farrell was gone, the rest of the band — including Navarro — stepped to the front of the stage to give the crowd a gentler farewell, appearing calm as they hugged one another, applauded the audience, tapped their hearts and offered a peace sign.

The altercation immediately blew up on social media, with no shortage of jokes — including countless Oasis comparisons — along with more serious concerns expressed for the well-being of the band members involved.

“I was there,” tweeted @deanasc1 on X. “The crowd was bemused. Half pissed the show ended early and half excited we may have seen the last Janes A show ever.”

“Jane’s Addiction broke up before Oasis omg,” came a typical tweet, from the user @Tribecalledflex.

On setlist.fm, the notations section for the Boston show offered an ironic juxtaposition of trivia about the gig, reading: “Note: Stephen Perkins’ drum kit was outfitted with balloons in celebraton of his birthday. The set ended early after Perry Farell punched Dave Navarro.” 

Press representatives for Jane’s Addiction and the tour promoter, Live Nation, could not immediately be reached for comment Friday night.
