Hey, did you know that about two weeks ago the bass player for the Dropkick Murphys, Ken Casey, beat up a fan onstage at one of their shows? He had good reason though.

They were playing a show in Manhattan and decided to let a bunch of fans onstage with them. Nothing unusual there. Then they started to play a cover of AC/DC's "T.N.T." Sounds like a good show so far. Then a man on the stage starts throwing up the Nazi Salute to the beat. Okay, hold up a minute. Now things are getting weird. That's when Casey walked across stage and according to reports, quote, "smashed him in the face, took off his bass and hit him with that, jumped on him, [and then] all-out chaos ensued."

Way to go man. Stuff like that has no place in a civilized society. The man was obviously removed from the show and Casey had a message for everyone, grabbing the microphone, he confirmed the feeling every one had, saying quote, "Nazis are NOT [EFFING] WELCOME at a Dropkick Murphys show." You can check out the scuffle below. The fight happens around the 1:15 mark.

But the story doesn't end there. Now the band is receiving threatening emails and they even posted one on Twitter, which contains excessive profanity, is NSFW, and can be seen by clicking Here. The band will be playing a series of shows in Australia starting this Saturday and they have yet to comment on the beat down or the threatening emails. We'll keep you updated if things change.
