It's the beginning of the end of an era. I'm sure you'll be seeing this on the VH1 special soon [if you watch VH1, that is]. For the rest of us, here is a 1987 music video by The Wiggles' own Quarrymen, The Cockroaches.
Anthony Field played guitar, Jeff Fatt played keyboards, and Field's brothers Paul and John did vocals. Greg Page was a roadie during one summer tour.
The comments are open for you to properly place The Cockroaches in the global rock & roll pantheon. The best I can do is "ZZ Top meets Wham! at a Mormon church dance."
