William Butler Yeats - Tom the Lunatic lyrics

Sang old Tom the lunatic That sleeps under the canopy: 'What change has put my thoughts astray And eyes that had so keen a sight? What has turned to smoking wick Nature's pure unchanging light? 'Huddon and Duddon and Daniel O'Leary. Holy Joe, the beggar-man, Wenching, drinking, still remain Or sing a penance on the road; Something made these eyeballs weary That blinked and saw them in a shroud. 'Whatever stands in field or flood, Bird, beast, fish or man, Mare or stallion, co*k or hen, Stands in God's unchanging eye In all the vigour of its blood; In that faith I live or die.'
