Apologies for a belated acknowledgement (I have been invited to a
round-table on the occasion of UNESCO's First International Jazz Day in
Paris, France, day after to-morrow, which kept me busy getting organized)
Thank you, everybody, who volunteered useful information both on- and
off-line. Excellent suggestions, more than I can handle, difficult
choices to be made...
