Above is a link shared from Alan Warren which will take you to an interview conducted by Studs Terkel with US International Brigader Eddie Balchowsky who served with The British Battalion in Spain. . Eddie lost a hand while fighting in Spain but he re-learned how to play the piano with only one hand as you can hear in the interview when he sings and plays Los Quatros Generales, The Peat Bog Soldiers and The Valley of Jarama. ( and a snatch of Home on the Range)
