Knicks owner James Dolan is also willing to toss music fans out of his shows if they dare instruct him to give the Knicks away — even while on stage.

So shows a recent video from a Chattanooga, Tenn., outdoor music festival in which a fan is holding up a sign that reads, “Quit Your Day Job. Sell the Knicks.”

According to the video, Dolan brings the fan close to the stage, admonishes him and asks him to leave the sparsely attended performance in which he is fronting for JD and the Straight Shot — his blues band. The video appears to be from the Pilgrimage Film Festival, which was Sept. 22-23.

The scene is similar to the one at the Garden last Saturday when he was videotaped berating a fan after the Sacramento loss for heckling him with “Sell the Knicks.”

Dolan said in a radio interview with Michael Kay this week that it’s his trigger because it is telling him “to quit and I’m not a quitter.”
