Well, that's a good reason for GB dividing into its smaller constituents - saves wearing out one tune.
There's one thing puzzling me, though..... The full name of Britain/UK/Blighty is "The United Kingdom of Great Britain and Northern Ireland"
But, in the Olympics, our competitors are called "Great Britain", even though the Norn Irish are in the same team. The team should really be the "UK" - nothing more or less.
Still, I like the division in Eng/Sco/Wal/NI etc for the Commonwealth Games, and it allows the Channel Islanders/IOM and others to get a chance.
