Officially, the anthem is the British one - which is the same in Liechtenstein, but with different words for some reason or other. When there's an "international" competition, the dreaded Danny Boy is dragged out because the tune doesn't offend anyone, although the loyalists refuse to acknowledge the existence of Londonderry, which they insist is called Derry. Me, I'd suggest the tune of McAlpine's Fusiliers, whatever that is called.
