Me: ex bass and guitar player in a couple of small jazzy dance and polka bands, and before that, long ago oboe and cello, now a violin maker. I used to play a bit of English concertina and now I'm getting back into it. The first time, 30 years ago, I was playing folk music like everyone does with it, but this time I'm trying to more mimic what accordions are doing, following the model of what the accordion sub with our first dance band did, so here I am, trying to learn what you guys do. . . . . .
