Yarrow now sings the line "A dragon lives forever, but not so little boys" as "A dragon lives forever, but not so girls and boys", to be fair to boys and girls. The original poem also had a stanza that was not incorporated into the song. In it, Puff found another child and played with him after returning. Neither Yarrow nor Lipton remembers the verse in any detail, and the paper that was left in Yarrow's typewriter in 1958 has since been lost.
