Jane’s Addiction singer Perry Farrell has apologized to bandmates and fans for “inexcusable behavior,” hours after news broke that the second half of the group’s reunion tour was being canceled after a fight broke out on stage Friday.

Etty Lau Farrell wrote that her husband “was a crazed beast for the next half an hour” backstage after the fight.

Perry Farrell's wife has spoken out on social media following her husband's on-stage assault on Dave Navarro last night.
