Pardonable misunderstanding there - the term "cloth-eared twit" referred to the fella on the radio whom kendall mentioned. I take it that kendall can tell the difference between his National Anthem and the Stars and Stripes Forever, or he would be a cloth-eared twit too.
My implication was that, if you have a radio announcer on an American station who can't tell the difference, he or she is a funny sort of American. (Or possibly tone deaf as King George V was, I believe - I think I read somewhere that the only way he could tell they were playing God Save the King was because everyone stood up for it.)
