The newest set of tracks coming to Guitar Hero III reach back to the long-forgotten days of Ska, when string and brass instruments frolicked together in a peppy, upbeat style of music. “Excuse Me Mr.”, “Sunday Morning” and of course their classic “Don’t Speak” will be available later today on the Playstation Store. All three songs that reach back to an era before Gwen Stefani shed her band and proved that there was some truth behind the “Don’t Speak” music video are already available on the Xbox Live Marketplace for the standard prices. All three tracks are the original master recordings.
