Free idea for anyone interested in making a mockumentary: a band that specialises in “Musak,” the type of music you hear in lifts or dental offices. They’re trying to make it to the big leagues — a well known department store, like a Myer or Macies — and they’re up against other bands getting better gigs, the Musak industry “big-wigs,” and their own shortcomings. Sort of like “Spinal Tap” meets the doctors waiting room.
