Activision has announced that in celebration of St. Patricks Day, they will be offering 3 free tracks for Guitar Hero III. This content pack contains all songs from the band, Dropkick Murphys and will be available “mid march” according to the press release. The songs are “Famous for Nothing,” “(F)lannigan’s Ball” and “Johnny, I Hardly Knew Ya.” I’ve actually never heard anything from this band before, but I’d still download this stuff, because hey, it’s free.
