Well, Brucie, you might think "Blowing in the Wind" is a traditional song, but I dont. Arguing about what you mean by"traditional" or "folk" may be tedious, but such is life. I know and love loads of traditional songs, and loads of non-traditional songs. The difference is pretty obvious to most people. Whether they can co-exist at a festival is something we can discuss, but obviously they are different things: otherwise how could we discuss if they can co-exist?
