Just to respond to something earlier in this thread when Captain Birdseye claims to have been one of the only people mixing concertina with clarinet on an arrangement. Now if you are talking about that one specific combination, you may be well correct, but I hope you aren't talking about the combo of woodwinds with concertina/accordion (whichever type you prefer), because there is most definitely precedent for that! Lest we forget your pal John Kirkpatrick's wife at the time Sue Harris and her oboe, and of course, Phil Pickett. Those are just the first two that leap out at me!
