You know, it's starting to look like some posters to this thread are missing the point or just fancy a little confrontation?
People I know in punk bands are in punk bands because they like punk. Which means they go and watch other punk bands. Ditto folk, pop, C & W, rock, blues etc. etc. etc.
So if someone is telling you there is a healthy population of "yoof" in their area playing Trad folk it's a pretty safe bet they are in an audience at some point watching the same stuff!! Obviously not the "answer" some want to hear to back up their own prejudice?
