WAV, my question about Barabara Allen is why is it acceptable for you to sing an English variant of a Scottish song, but for an Englishman to sing something like House of the Rising Sun would be an abomination?

You haven't answered it.

Now, without ignoring that one, on to my other questions.

1) What do you think of Noel Coward, is his music not English?
2) explain in greater detail what you mean by nationalism with fair trade. Then again, maybe you have cause for retinence, hmmmm.
