Steve Harwell, the lead singer of Smash Mouth, broke into a profanity-filled rant and threatened to beat up people who threw bread at the beginning of a performance in Fort Collins, Colorado, on June 14.
Smash Mouth was the final act to play at the Taste of Fort Collins food and music event.
According to the Coloradoan, one of the vendors at the event gave away loaves of bread.
USA Today reports that Harwell cursed the crowd and dared the bread throwers to come up on stage, but a security guard stood between the singer and the audience.
"You throw one more piece of s**** on the f****** stage. I’m gonna come find your ass, I’m gonna beat your ass, whoever the f*** you are out there, OK? You want to be bad ass, come up here, come on! Walk your bad ass up here, come on, come on stage! Come on stage bad ass! ! Come on! Come on stage! You bring your ass on stage whoever is throwing s*** at me. I will tell you right now I will beat the f*** out of you, OK? You're p**** punk b******!"
Smash Mouth began playing the opening notes to its hit "All Star" as some in the audience booed Harwell.
