Here you will find the Poem A Man Young And Old: X. His Wildness of poet William Butler Yeats
O bid me mount and sail up there Amid the cloudy wrack, For peg and Meg and Paris' love That had so straight a back, Are gone away, and some that stay Have changed their silk for sack. Were I but there and none to hear I'd have a peacock cry, For that is natural to a man That lives in memory, Being all alone I'd nurse a stone And sing it lullaby.
