This was recorded and released as part of a Stinson 78 rpm record album in the late 40s or early 50s. I believe it may have also been included in a 10"lp that was released in the mid to late 50s, called, I believe, "Songs of the Lincoln Brigade." Most of the songs, but not this one, were sung by the Almanac Singers. Although it was not a Spanish Civil War song, it might easily have been sung in Spain by members of the Lincoln Brigade.
