"War" first appeared on Bob Marley and the Wailers' 1976. The lyrics are borrowed from a speech made by Ethiopian Emperor Haile Selassie I before the United Nations General Assembly in 1963. http://en.wikipedia.org/wiki/War_(Bob_Marley_song)
Dima, absolutely true! Music is a kind of effective weapons against war. As it goes ' ...we are confident in the victory of good over evil '.
