"there are fewer people around doing mostly traditional music these days"

I think that's less true in the UK these days - it would be relatively easy to put together a festival of almost entirely traditional music and song, with guest artists right across the age range. If I had time, and the energy to get some sponsorship as a safety net, I wouldn't mind having a go at setting one up. And there are still festivals over here - not just the sort that Synbyn's talking about (which in terms of context are probably closer to the tradition than those booking guests), which manage to book mostly traditional-style performers, and are very successful.
