Dear Mick Lowe,I'm pleased to encounter someone who'se thinking along the same lines as myself. (Apart, that is, from McGrath of Harlow - but he and I are partners in crime from way back.) If you'd like to read my thoughts on the subject in more detail, see my article "England, whose England?" in Rod Stradling's web magazine, Musical Traditions at http://mustrad.org.uk (where much else of interest can be found. I'd like to hear your response to it (or anyone else's for that matter).
Wassail!
