As long as we're on a Southern Rock theme, this performance of "Free Bird" at the Oakland Colosseum is basically the epitome of 1970s stadium rock.  Just a few months later, lead singer Ronnie Van Zandt and guitarist Steve Gaines (the one with the short beard) were killed in a plane crash.  Indeed, now the only surviving members of the band from that day are guitarist Gary Rossington (the one playing slide guitar) and drummer Artimus Pyle.  (That huge Confederate flag in the background is certainly jarring now, but it generated little controversy back then, although might have something to do with the striking racial composition of the audience!)
