Smash Mouth's lead vocalist Steve Harwell didn't take kindly to pieces of bread being thrown at him on Sunday night during the finale for Taste of Fort Collins.

Harwell caused quite a stir during the band's performance, first yelling profanities at the crowd, then being subdued by a security guard and finally walking off the stage ahead of the encore.

He lost his temper when concert attendees started throwing slices of bread in the air. A few pieces reportedly landed on the stage.

Loaves of bread were being given away for free at one of the Taste of Fort Collins vendor booths.

Fans started booing as Harwell spat out a string of insults.

The entire incident lasted about three minutes.
