The title is a play on the Bob Dylan song "Subterranean Homesick Blues
." In Humo
magazine July 22, 1997, Yorke said: "A tribute to Dylan's 'Subterranean Homesick Blues.' (sings) 'Jonny's in the basement mixing up the medicine, I'm on the pavement thinking about the government.' Do I really hope to be on a spaceship? Why not. I believe there are aliens under the ground. I want to see them. I want to see ghosts. I want to walk on the street smiling, knowing that there are little green creatures with incredible large brains and big, beautiful, black eyes, that are filming us with their video cameras."
