Most of the people who turned up at the Bad Religion concert on Sunday night weren't even born when the band formed in 1979. Try that with any other rock band that's been around 20 years. Take Def Leppard or Deep Purple, for instance - they're playing at the classic rock fest for fans whose age exceeds their waist size. It says a lot for the credibility of Bad Religion that they're so popular with teenagers. Teens determine what's cool and what's not in the world of popular music - and Bad Religion is definitely cool. So instead of a horde of wrinkled old punks sporting mohawks sprayed with Grecian Formula, the Shaw Conference Centre was packed with more than 2,000 high school kids, moshing furiously as the venerable punkers plowed through nearly two hours of politically charged, rapid-fire music. Not one song was what record industry people refer to as a "hit." Bad Religion doesn't know the meaning of the word. This matters little to the band's loyal young fans. Not having massive commercial success is, in fact, part of the punk mythology. (That, and ignoring any objects thrown on stage - that's punk, too.) Bad Religion is more about message than music. Although lead singer Greg Graffin looked like a college professor on his day off (and he could be as soon as he gets his PhD), he was the perfect anti-establishment, anti-rock star. While his bandmates pounded out a polka-tempoed din of rebellious noise, Graffin delivered one long sermon. He preached independent thought, the virtues of questioning authority, the perils of organized religion, the inherent corruption of government, the fact that we're all going to hell in a handbasket, and so on. Songs included Against the Grain, Them & Us, Faith Alone, No Control, American Jesus and "the song that started it all" - We're Only Gonna Die. An affable frontman, Graffin also offered advice to would-be punk musicians: "Don't listen to your parents when they tell you to turn it down. Trust me on that." One wonders if the crowd-surfers absorbed the deep social-political implications of Bad Religion's music, but perhaps they've already been converted. Besides, it's the spirit that counts.
