The Dropkick Murphys played a gig in New York on the 13th and were having a huge party. During some encores, they invited the audience up on stage. And while they ripped through AC/DC's "T.N.T." a neo-nazi began Hitler saluting on stage. That didn't go over very well at all.

When bass player Ken Casey saw the salutes he IMMEDIATELY ran over to the guy and began wailing on his ass! I mean he straight up clocked the a-hole and kept going. when things began going back to normal he grabbed his mic and reported that "Nazis are not f%$@ing welcome at a Dropkick Murphys show."
