Public Enemy No. 1

On July 4, 2011 Megadeth debuted a new song entitled "Public Enemy No. 1" at a show in Hamburg, Germany. According to the Public Enemy No. 1 Songfacts, the writing of the song was started by the band during a soundcheck in Croatia in 2010 and completed in Vienna, Austria a short while later. Mustaine has said that "Public Enemy No. 1" was written about 1920s gangster Al Capone. The inspiration was a possible haunting incident while the band was recording in an old building in Tennessee which Mustaine described as being a "hideaway" of Capone's. Ellefson revealed in an interview that "Public Enemy No. 1" would be released as a single.
