Ah but I know where you live Guran!!
I am not an English Concertina player, but I have been listening to hours of it.I think it is a remarkable and versatile Instrument,I have completely changed my mind about it's capabilities. Jan Elliott plays Morris style on the English with bounce,chords and feeling for the dance.Henrick has done a fine set of Irish Tunes on his slightly modified English Concertina on English International, as has Tim Jennings in a completely different style backed by lovely harp playing.(Perhaps a more American Irish style).
If you consider an Irish person that likes the sound of a concertina and 99% of players play ITM on an Anglo then that is the Instrument they will buy.Dick mentioned to me Ms O'Dowd who was Irish Concertina Champion, playing the English, about twenty or so years ago.Sadly she stopped playing shortly after to raise a family.If she had continued the Irish Concertina Scene could have been completely different by now.
