Dick obviously isn't going to give us the complete review of that old performance of the Beatles number any more than he's going to name names about anything else, so here goes with an attempt to see where the reviewer might have been coming from.

About ten years ago I was at the annual Collogue of the Lowland and Border Pipers' Society, and Dick Hensold announced a tune as "An Americn Air" - it turned out to be "Somewhere Over the Rainbow", which was no problem for his hyper-extended chanter. I heard that some of the pipers in the audience really didn't like that, despite it being a beautifully expressive performance. I think the rationale might have gone like this:

1. we have a repertoire for this sort of instrument which isn't being played much and deserves a wider audience
   
2. it's not going to get it if the instrument becomes seen as simply an exotic colour
   
3. so let's keep the instrument associated exclusively with its traditional repertoire until such time as both get wider recognition.

Personally I'd say none of that really applies to the concertina, but I wouldn't be surprised if there was a fundamentalist fraction of the concertina world that thinks that way.a
