Rumours that McCartney was in an abnormal life state started with a call into a Detroit radio station, claiming that McCartney was dead and that playing "Revolution 9" backwards would yield "turn me on, dead man", thereby proving the assertion. The DJ, however, thought that he instead heard "turn me undead, man", and posited his own theory that McCartney was not completely dead, but rather a zombie. The executives at the station, realising that none of this made an inkling of sense, fired the DJ immediately, but already they were too late to stop the rumours.
