Hi hi,
I don't wanna sing, if it don't mean a thing.
That said, there are times and places for the right song. I wouldn't do Masters of War in a bar, unless it was a request.(I admit to being a total slut when it comes to requests. I've played Puff The Magic Dragon in a biker bar. They asked. I played. What can I say?)
You can be damned sure, however, that I will play The Band Played Waltzing Matilda at every Remembrance Day/November Coffeehouse. Politics is a part of folk/people's music, and it's part of the job to be political.
Apolitical art is beige. It's a pleasant hue, but not one I'd put on a protest sign.
Cheers
Owl/Mart.
