'Culture,' Norman Mailer once said, 'is worth huge, huge risks.' Billy Bragg seems prepared to take those risks, and his rhymes of resistance and years of political campaigning have established him as the doyen of British protest music.

I also reached out in search of explanation. Fearing there would be no straight answer, I wanted to hear the crooked answer.
