Late reply to Ralphie to your message of 1st Oct 7.57am in which you ask:
Does any of this really matter?
Not really...does anything that you can't control? I just meant to assert that if there was going to be such a thing as a National Instrument - why not the concertina? It's more appropriate than say - a thumb piano for instance?
If you mean should I lose any sleep over it, then - no....but yes - I think it matters some....it depends how deep you want to go with it...:-)
I'm glad you agree with me however...
