I give you no argument, all British music, even when it is deliberately imitative of American music, is an entirely different beast. Not that it's bad--we certainly listened to, and loved, a fair number of British bands--and there was a certain esoteric prestige associated with listening to say, Lindisfarne--and more than a few American groups were heavily influenced by British groups--

I've forgotten my point, but no matter, as since this is a music, not a political one, no one is likely to notice;-)
