There have been enough horse brasses and pointy hats and leather tankard threads without the onus of proof being on me for that one.
My impression of newer bands is that they move through folk clubs fairly swiftly for the festival circuit. Yes, I can think of exceptions but as a rule of thumb that is the case. Why worry about what a self appointed folk guardian thinks when you have a ready audience who don't GAF either way?
