Some of the more famous nuclear war songs include: "99 Luftballons" (1983) by the German group Nena, which depicts accidental nuclear war begun by an early-warning system identifying a group of balloons with enemy bombers or missiles; and Bob Dylan's "A Hard Rain's a-Gonna Fall" (1963), which premiered shortly before the Cuban Missile Crisis. He also made reference to nuclear weapons in his song "With God on Our Side" released as the third track on his 1964 album "The Times They Are a-Changin"'.""But now we have weapons, of chemical dust...if fire them we're forced to...then fire them we must..."". In many cases the allusions to nuclear war are not explicit, however. Steely Dan's "King of the World," on the album "Countdown to Ecstasy" is an example of upbeat music and very downbeat lyrics which give a very bleak picture of the post-nuclear world.
