The lyrics from this song are taken from Peter S. Beagle's 1968 novel "The Last Unicorn". In the novel, they are sung by the owner of the Midnight Carnival, a witch, who is magically impersonating a pitiful character named Elli for the final act of the carnival.
Lyrics
what is plucked will grow again,
what is slain lives on
what is stolen will remain,
what is gone is gone
what is sea-born dies on land,
soft is trod upon
what is given burns the hand—
what is gone is gone
what is gone is gone
who has choices need not choose;
we must, who have none
we can love but what we lose,
what is gone is gone
here is there and high is low—
all may be undone
what is true no two men know:
what is gone is gone
what is gone is gone
what is gone is gone
