Toto keyboard player David Paich
wrote this song, which is inspired by the 1971 movie THX-1138
, the first full-length film directed by George Lucas of Star Wars
fame. Writes Paich: "This movie is set in the 25th-century in a totalitarian state where mankind is stripped of any individuality. People are numbered drones, and a government-enforced program of sedation controls the populace. Lucas used THX as the name for his movie theater sound system."
