An interesting debate. It makes me realise how blessed we are in the Holme Valley with sessions that aren't "run" by anyone, most are attended by tolerant and appreciative people. There is the occaisional melodeon / accordion that can't hear the tune that a recorder or whistle has started and hijacks it, but there are also the variety of a mixed (singing and instrumental)session, a "normal" (not so much diddly dee with a smattering of french amongst the english) and a diddly dee "biased" session on different thursdays. I've never heard any argumeents yet and don't expect to. After all, its about making music and having fun isn't it?
