Video of a fight at a college football game has gone viral.
That's because the man throwing the punches was part of the marching band.
He played tuba for Texas Southern Ocean of Soul Marching Band and was in the stands when a heckler approached him during the weekend game against Jackson State.
Words were exchanged, and that's when the musician knocked the fan out cold.
He then went back to performing. Texas Southern is investigating the confrontation.
