To Banjiman: it's not just in England, of course, where folks are singing with American, rather than their own, accents, performing the music of other nations, etc.; but I can't think of any nation where this process is occuring more than it is in England - Show of Hands, e.g., may not agree with me on everything, but they have also felt the urge to at least try and do something about it, hence, "Roots".
