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".
The Dire Straits were a popular musical act in the nineteen eighties.
