If you've ever had the chance to see the documentary film about The Clash called "Rude Boy," you'll know immediately why Jack's analogy is so apt, especially the emphasis on the opportunity for band and audience to interact. There's a memorable scene where the band talks about that dynamic and I recalled it vividly as I read your post, even though it's been years since I saw the movie.

Thanks for reminding me of a great memory and giving me something to think about.
