I think there's a problem that anyone who is successful gets slagged off automatically by some people in the folk world, just because they are successful.

Artists like Seth Lakeman and Show of Hands are very talented and have worked hard to get where they are, just as Vin Garbutt and Martin Carthy before them. Show of Hands have been going for the best part of 20 years, so they are hardly an overnight success. Whether you like their music or not (and I do happen to like them), they have helped raise the profile of folk music with the general public, and IMO that has to be a good thing.
