Folk demonsrtation against facism and racism is a fantastic idea.
Why stop at single demonstration.

Why not include information in programmes of little beer and folk fests? Why not broach the subject in folk clubs and create some sort of charter? Why not ask artists to include statements in sleeve notes of their albums? Why not talk to schools and parent associations and ask to do demonstrations of morris and folk music? Invite parents from all ehtnic background to visit a practice or session?

Just a thought or twenty.
