Some while ago, a bunch of us were playing tunes in the back bar of an English country pub while the locals were watching some sort of sporting fixture on the telly in the front bar. (Dunno. Probably involved a ball.) England were getting thrashed by Ireland and a fan was heard to shout "and there playing bloody Irish music in the back room." Could we have shouted back "No. It's Anglicana" or even "No. It's Musica Britannica."? I think not.
