"Viva la Quinta Brigada" (listed as "Viva la Quince Brigada" in later recordings) is a Christy Moore song about the Irishmen who fought in the Spanish Civil War against Franco. The title was inspired by a Spanish song about the war, 'Viva la Quince Brigada'. Moore wrote this song choosing to focus on the Irish socialist volunteers (who in later years became known as the Connolly Column) who were a small contingent within the 15th International Brigade. The song was inspired by Spanish Civil War veteran Michael O'Riordan's book Connolly Column.
