This haunting song was composed and written by Scottish folk singer, Ian Campbell, and first released in 1963 but made famous by Simon and Garfunkel, who included it on their first album, Wednesday Morning, 3 A.M., one year later. It tells of the horrors of a nuclear blast and was written at a time when the movement for nuclear disarmament was growing. It became the official song of CND -- the British organisation Campaign for Nuclear Disarmament.
