Character Analysis
Viv's the tripped-out keyboardist of the group, who gets one of movie's classic lines when asked by Marty about his philosophy of life; "Have a good time, all the time." Marty asks him what he'd do without rock and roll:
VIV: I'd probably get a bit stupid and start to make a fool of myself in public, 'cause there wouldn't be a stage to go on.
Viv's an early adopter of computer games—we see him on the tour bus playing some primitive version of a Pac-Man type planet-eating game.
