A Man Young And Old: X. His Wildness by 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.
