What format would a contest take if you were in charge? I would go for a set test piece, with no more than 10 bands in each section, a pre-draw, open adjudication by 2 adjudicators, no soloist prizes, each section announced after it has finished, a minimum of local dignitaries - the adjudicators can do their own announcing. I would also have all of the results announced. I know this would be a bit harsh on the band that came last, but it would stop all the confusion and rumours that happens at most contests when nobody knows where anybody else came apart from the top few. And no National Anthem!
