This included such songs as "There's a Valley in Spain called Jarama" and "Viva la Quince Brigada". In 1960, this collection was re-issued by Moe Asch as one side of a Folkways LP called "Songs of the Lincoln and International Brigades". On the other side was a reissue of the legendary "Six Songs for Democracy" (originally recorded in Barcelona in 1938 while bombs were falling), performed by Ernst Busch and a chorus of members of the Thälmann Battalion, made up of volunteers from Germany. The songs were: "Moorsoldaten" ("Peat Bog Soldiers", composed by political prisoners of German concentration camps); "Die Thaelmann-Kolonne", "Hans Beimler", "Das Lied Von Der Einheitsfront" ("Song of The United Front" by Hanns Eisler and Bertolt Brecht), "Der Internationalen Brigaden" ("Song of the International Brigades"), and "Los cuatro generales" ("The Four Generals", known in English as "The Four Insurgent Generals"). As a self-described "split tenor" (between a tenor and a countertenor), Pete Seeger was a founding member of two highly influential folk groups: the Almanac Singers and the Weavers. The Almanac Singers, which Seeger co-founded in 1941 with Millard Lampell and Arkansas singer and activist Lee Hays, was a topical group, designed to function as a singing newspaper promoting the industrial unionization movement, racial and religious inclusion, and other progressive causes. Its personnel included, at various times: Woody Guthrie, Bess Lomax Hawes, Sis Cunningham, Josh White, and Sam Gary. As a controversial Almanac singer, the 21-year-old Seeger performed under the stage name "Pete Bowers" to avoid compromising his father's government career. In 1950, the Almanacs were reconstituted as the Weavers, named after the title of an 1892 play by Gerhart Hauptmann, about a workers' strike (which contained the lines, "We'll stand it no more, come what may!"). They did benefits for strikers, at which they sang songs such as 'Talking Union', about the struggles for unionisation of industrial workers such as miners and auto mobile workers. Besides Pete Seeger (performing under his own name), members of the Weavers included charter Almanac member Lee Hays, Ronnie Gilbert, and Fred Hellerman; later Frank Hamilton, Erik Darling, and Bernie Krause serially took Seeger's place.
