While on tour in Australia in December 2010, the Dropkick Murphys wrote to Springsteen to invite him to participate on their upcoming album Going Out In Style (released March 1, 2011). Bruce quickly recorded his duet part for "Peg O' My Heart". When he opened the email with Bruce's vocal file, Murphys singer Ken Casey told Rolling Stone, "I was like a kid opening a present on Christmas morning."
