The middle-class has as much right to song as any other class. Part of the problem that is beginning to be felt is the restrictiveness of ideas and categories of music. (Recall the 'uproar' when Fairport did trad stuff with electric instruments. Youda thought civilization was ending.) The folk world needs ways to draw in younger blood. If it doesn't, the music will be remembered as a lost art. Trad music is not sacred. Nor is 'the blues'. Nor is ANY music. It belongs to all people. Everywhere. Even rich people.
