Surf Curse; 1st show of a 2 night run

The guy being punched on the ground was involved in a situation at the front of the stage at the end of the show. They pulled him out and he had a bloody nose. After the show, he was standing outside, clearly inebriated, when the assailant (guy in the black sweatshirt/jeans) got in his face and accused him of inappropriately doing something to his girl. The guy denied it, but the assailant didn’t like that answer so he punched him. The guy countered back then that’s when the video starts. Cops and paramedics were called, and a detective was interviewing witnesses. All of those involved were at the Surf Curse concert.
