First published as 'An Old Song Resung' in The Wanderings of Oisin and other Poems (1889).
Originally an old Irish folk song, Yeats turned this into a poem as a dedication to oral tradition.

I know what this poem means because I have lived it.
If there were one thing in my life I'd do over again, it would be to marry that girl instead of leaving her because I took life and love far too seriously.
I was young and ambitious, too strict with myself and with others, too quick to find fault with myself and with others..
I thought if I worked harder to better myself, life would reward me with an even better woman to marry.
I see now what a treasure I threw away so many years ago--I am sad, and also horrified at the miserable life I have made for myself, and--forbid it God--possibly for her, too.
