"As for the lack of degree-level qualifications in older generations: I'm sure many of the long-respected stalwarts of the folk scene would have jumped at the chance of studying and playing with some of the best musicians in the country, had such an opportunity been available to them."
As regards Concertina song accompaniment, no, I would still prefer to work my own style out, there is not a single other english concertina accompanist other than Steve Turner[ who plays a hybrid bass baritone anyway] that I have heard who Interests me.Anglo is a bit more intriguing
Alistair Andersons style [ good in his own way] is of no interest to me either, if there was someone who taught jazz concertina, maybe.
These days with some good you tube lessons ,one can teach oneself easier, the most important thing in my opinion is to have ones own distinctive style,
examples are Carthy, Jones ,myself, Steve Turner, THE FIRST TWO COULD NOT BE CONFUSED,NEITHER COULD THE LAST TWO.
The degree course is good up to a point,as long as students do not copy slavishly, but use it merely as a starting point to developing their own style.
my concertina style is based on guitarist, John Hurt, but unless i told you,you would never have guessed.
