Brothers, I am coming
Will you call me on?
What are you becoming every dawn?
Mother, you have cursed them
Eleven feathered sons
Beneath the shadow of their wingspans
I will run
“Eleven Feathered Sons” by Leslie Hudson, based on the fairy tale The Wild Swans. Lyrics available on Bandcamp.
For another neat (and tonally very different!) interpretation of a closely related folktale, check out Queen of Spindles by Talis Kimberley.
