Un du ackerst ... Yiddish translation of: Bundeslied für den Allgemeinen deutschen Arbeiterverein (Federation Song for the German Workers' General Union) by Georg Herwegh, 1864. Herwegh (1817 - 1875, "The Iron Lark") was a well known poet of the 1848 revolution, fighting for socialism and a free German Republic. By later Young Socialists the song was attributed to Erich Weinert, a writer in the German Democratic Republic. This is utterly false.
A fine song is also: Oyf'm weg nach Simferopol(click) about farming on the Krim, when Jews were allowed to own land after the October Revolution. (A Treasury of Jewish Folksong / by Ruth Rubin. - New York : Schocken Books, 1950)
