Riff Randall (from Rock 'N' Roll High School). Riff would have been my rock 'n' roll partner-in-crime in high school. We would have attended every rock concert we could possibly manage together. We would wear matching shiny outfits, pigtails in our hair, and run around shouting "gabba gabba hey!"
Jam (from Detroit Rock City). Jam would have been another one of my closest chums. After school, I'd go watch him practice and rock out on his drums and then talk endlessly about the amazingness of KISS.
The Spinal Tap guys. Who wouldn't want hang out with Spinal Tap, the coolest, wildest rock band on the planet!?
