Premise: The Sultans of Ping FC are an Irish band formed in 1988 by Niall O'Flaherty, Pat O'Connell, Paul Fennelly and Ger Lyons. The band's name is a play on the Dire Straits song "Sultans of Swing", dating from a time when "it was sacrilege to say anything whatsoever funny or nasty about Dire Straits".
Hypothesis: The lead singer of the band once broke his arm on stage when he tripped over the microphone stand.
