The fact that the Anglo concertina seems to have been overwhelmingly associated with 'Folk' music, Morris music and Irish traditional music provides no logical reason to fear that if interest in these styles of music were to seriously decline the Anglo concertina itself would necessarily be heading for oblivion... but, as things are at present, it would obviously have a significant effect.
I guess that there are those like myself who have very limited interest ( if any ) in Folk, Morris or ITM yet derive endless pleasure from playing ( or at least attempting to play ) the many other totally different styles of music to which the Anglo is equally well suited.
I couldn't agree with you more rod.And as for availability, one of those cheap chinese boxes has lasted me years and given me dialy enjoyment the hole time.That being said can't wait to make an upgrade!
