Sing Out!" was an American quarterly journal of folk music and folk songs that was published from 1950 to 2014. Co-founded by Pete Seeger and Irwin Silber, Sing Out!'s stated mission was "to preserve and support the cultural diversity and heritage of all traditional and contemporary folk musics, and to encourage making folk music a part of our everyday lives." The contents would typically have been a collection of articles, tutorials and arrangements for songs. This example includes the flexi-disc that came with the issue, and a number of articles that reflect the concerns of the time, notably the end of the Viet Nam war.
