We still have regular chart success from folk acts. Bellowhead, Show of Hands and Seth Lakeman to name but three have had chart success and are in the public eye through radio and TV. I imagine they all have agents who played a part in getting them where they are. Of course some may dispute that they are folk artists but the public perception is that they are and, as such, are contributing to the revival. So, in some cases, I think agents impact could be possitive. Just my 2p.
