The threshold? For me, the condition for it being a folk festival is that people there have got to be more than passive spectators, because for me the difference between folk and "other" music is the breakdown of "us-and-them" where only a select few get to have a go. So workshops, singarounds, sessions, open-mikes, dances - if you ain't got them, it ain't a folk festival.

And the further away you are from the performers, the less likely it is to be a folk festival.
