You seem to be suggesting that all of us who have spent our lives being obsessed by folk music will somehow drift off in other directions once this is over. A very negative and doom laden attitude! There are enough of us obsessives in every part of the UK to ensure that this will continue in whatever form; concerts in museums, churches, village halls, etc.; singarounds, sessions, grass-roots festivals like ours, taking the music into other areas like schools.

It's obvious from what you see on the web that huge numbers of people are furiously woodshedding away at the moment and will emerge from this with new material better performed. They'll find some way to show it all off - but folk clubs are irrelevant to the improvement and probably won't be the venue where it emerges. Some traditional performers experienced a step change in power after they retired and could spend more time at home practicing - Billy Pigg is an example. We may see many more like that.
