last night, I was helping an anglo player with some irish tunes.
we had a few tunes together after the lesson,couldnt tell the two sytems apart,unless one listened very very carefully.
he didnt have any problem being helped by an English player,when there arent many concertina players around,people dont seem to be so precious about systems.
I have never encountered any problem with the fingerplate on the English ,or the traditional layout,neither as far as I know have SteveTurner,Alisatair anderson, KeithKendrick,LeaNicholson,DamienBarber ,SaraGraves.but if other people want to change and add make adjustments ,why not?
live and let live.
As long as people dont start lecturing me on what I should do,when I dont wish to alter my concertina.,im easy.
