"Less Than Zero" is the eighth track on Elvis Costello's debut album My Aim Is True, and the first Costello single that Stiff Records released. In the liner notes to the Rhino edition of the album, Costello writes: "Less Than Zero" was a song I had written after seeing the despicable Oswald Mosley being interviewed on BBC television. The former leader of the British Union of Fascists seemed unrepentant about his poisonous actions of the 1930s. The song was more of a slandering fantasy than a reasoned argument. The song later provided US author Bret Easton Ellis with the title of his debut novel.
