John Mellencamp was doing a show Sunday night in Toledo, Ohio. While he was telling a story about his grandmother, an impatient heckler called out for more rock, less talk. It turns out Mellencamp is quick on his feet with the comebacks. (He calls the guy a "CS" and asks a roadie to find the guy.)
The video is not bleeped. It has strong profanity from John and people in the crowd.
Of Note: A guy also yells "I'm sorry John" at :32, but it's unclear if that was the original guy who yelled for more music.
