Smash Mouth singer Steve Harwell threatens fan in wild concert video

Smash Mouth lead singer Steve Harwell went beyond potty mouth during a recent show.

The band performed a concert in upstate New York on Saturday. In a video of the event, Harwell, 54, can be seen slurring his words, threatening the audience and seemingly giving a Nazi salute to the crowd.

TikTok user @doesthisfeelgood caught the wild show during the Big Sip beer fest in Bethel, NY, and the footage has since been making the rounds online.

The clip showed the band having technical issues during the performance as they struggled to play over a seemingly broken PA system.

Harwell could be seen dropping his drinks, swaying back and forth onstage and flipping the bird while cursing multiple times.

“I’ll f—king kill your whole family, I swear to God,” he screamed to one fan in his audience. In another explicit rant to a different audience member, he claimed he would never leave the house if he could masturbate better.

Reps for Smash Mouth told The Post on Tuesday that the incident was related to ongoing health issues and Harwell would be retiring.

“Steve has been dealing with long-term medical issues over the last 8 years and during his last performance at the Big Sip stage, he suffered numerous symptoms directly linked with his current medical situation,” the rep said. “As of today, Steve will be retiring from Smash Mouth to focus on his physical and mental health.”

Smash Mouth was blasted once before last year when they decided to play at the Sturgis Motorcycle Rally in South Dakota during the height of COVID-19.

Harwell recently announced he would be taking a hiatus from performing due to several ongoing health issues. His rep confirmed to TMZ that he would be taking a break to deal with cardiomyopathy and heart failure, which forced him to miss a few performances.

He currently manages his condition with medication and decided to change his lifestyle, his rep revealed at the time.
