"... the Who shot Roy Race? saga that followed hot on the heels of Who shot JR? (it turned out to be an actor sacked from playing Roy in a TV soap), which led to Sir Alf Ramsey stepping in as caretaker manager; the earthquake that ripped across Mel Park and led to Melchester playing temporarily at Wemb¬ley many years before Arsenal thought of it; and countless tours to South Amer¬ica that always led to the team being kidnapped."
Blimey this is an old thread. Anyhow, your answer is... John Paul, as in Pope John Paul II who was shot (and subsequently recovered) the year before this song was released (as was the fictional Roy Race), and John Lennon had been shot a few months earlier than that.
