As a result of a recent scrum between a Neo-Nazi and Dropkick Murphys' Ken Casey in New York, the band have begun receiving threats from Neo-Nazis in Australia. The band's management received an email warning them not to show up in Australia, a screenshot of which (that the group tweeted) can be seen below.

DKM invited the crowd on stage in New York while they performed the cover of AC/DC's "T.N.T." and the offending patron decided to perform a Nazi salute to the assembled throng. This didn't sit particularly well with bassist Ken Casey who shoved him before band members told the audience: "Nazis are not fucking welcome at a Dropkick Murphys' show."
