The middle classes are also people, many of whom emerged from working class roots. I'm probably seen as 'middle class' by people who choose to look at the world in that rather limited way, but I'm descended from artisans on both sides of my family, so when I hear a traditional folk song I hear my own history echoed there.

You can't neatly divide people up into classes anymore, the world has moved on. If a university lecturer wants to organise a folk club, great. Someone's got to do it - does it matter what they do for a living?

There will be folk songs as long as there are people walking the Earth.
