As a resident of Faversham it pains me to hear this beautiful medieval town described as Chaversham. I'm fairly sure that we have no more than our fair share of young people who drink too much and hang around in the streets making a racket and intimidating the children (which what I'm assuming you mean by the chav reference) but it really isn't what defines either the town or us residents.   

The Hop festval is indeed a town festival not a folk festival but because the pubs are open late and there's plenty of music of all kinds about it's perhaps not surprising that all sorts of people are drawn to come and enjoy it.

I'll declare myself as a folkie just so's you have some sense of where these comments are coming from. I rarely contribute to these kinds of discussions because the written word is so easy to misunderstand and people's views can often seem offensive when perhaps they're not meant to be in this medium. I just wanted to advocate for the town I live in that some of you visitors perhaps only see from a jaundiced perspective because you have expections that the festival was never designed to meet.
