Yes Mike, Bob and Ann were playing as Cheshire Waits when they joined us in Chester Waytes, which was a seven-piece outfit. I never actually saw them performing as Cheshire Waits, but I think they did a mixture of folk and early music, and used a mixture of traditional and early instruments.
Speaking of fingerings, do you know you can extend the range downwards on the crumhorn by under-blowing? It's a technique that was used in the early days, apparently. I suspect that it may only work on lower - pitched instruments. It works on my tenor, but not on my alto. It probably depends on the instrument, and on the reed, but it's worth the experiment. If you play the normal range down to C (on the tenor), then repeat the fingerings for E, D and C, while reducing the breath pressure, you should get B, A and G. It takes a bit of practice to get the right pressure, and, as I say, it might not work, but give it a go! John Kelly.
