Smeg and the Heads
In the 1989 "Timeslides" episode of U.K. sci-fi series Red Dwarf, Dave Lister (Craig Charles) gets to glimpse his past self, as a 17-year old practicing the song "Om" with his garage, or whatever they use for garages in the future, band. "Om," also known as "The Om Song", had a very simple lyric (can you guess?), and a lot of noise.
Bill Steer and Jeff Walker of real Liverpool grindcore act Carcass, played, respectively, band members Dobbin and Gaz. Emile Charles played young Lister.
