Sing, as in Madrid the rifle-shots were drowned by voices singing, hearts made warm from acts of self-defence, the baricades thrown up with kitchen pots and mattresses, confessionals and cots against the onslaught of machine-gun storm. Sing, sing out ! as lines collapse, re-form as bombs hiss past, explosion blots the screaming child-- all Europe falling now. Sing, till the crumbling ruin of our world becomes a stanping-ground for brotherhood: Sing till the barricades of life are hurled against oppression--sing till banners blaze in one imperishable cry unfurled!
