this year, on the main stage before roger waters' set, many bob dylan tracks were played over the speakers. prince played what i believe to be an exclusive to coachella Creep cover. and during waters' set an airplane was promoting muse for a good while. i know it is a huge stretch to be wondering about all this, but crazier things have happened, and it's fun to speculate. have paul and GV done "games" and hints like this before?
