Lyrics:

Hear the sirens in the afternoonEnemy missile gonna hit us soonCasualties will be giganticRun down the street and panicPush the button babyFreak out, overreactPush the button babyAttack Attack Attack AttackLiving underground is no funCan't talk to anyoneAin't got no outside influenceStaying alive by civil defenseTurn your TV to a defense stationThey'll provide emergency informationHide in a cave if you know what's bestAnnouncer says, 'No, this is not a test'
Husker Du Push The Button
