Despite coming a couple years before the band hit it big, and featuring a song that was never really released, Blondie's 1975 CBGB's performance of "A Girl Should Know Better" is as clear an example of the group's draw — particularly that, obviously, of singer Debbie Harry — as you're likely to see. The song is hardly one of the group's best, but Harry dominates it with 100 percent confidence, alternately alluring and confrontational, demure and winking, girl-next-door and bad-ass pop diva in one. And after watching her in the undersized white shirt and necktie here, you can only imagine how she must have been rolling her eyes when Avril Lavigne came through.
