Wally and the Falcons

Band at the center (or centre, since it's Australian) of Oz (aka Oz: A Rock 'n' Roll Road Movie aka 20th Century Oz), a 1976 down under parody of/tribute to The Wizard of Oz. Rather than dirt farmers (that was what the Gales were farming, right? Dirt?), the real-world analogues of Dorothy's adventure were rock musicians. Dorothy, a groupie in this incarnation of the story, hits her head due to a car accident and has an adventure with a brainless surfer, a heartless mechanic, a cowardly biker, and (naturally) a Wizard. The film, whose musical score is by Ross Wilson (frontman of real Australian rock bands Daddy Cool and Mondo Rock), didn't do so well upon release, but has become a cult film.
