Try looking under the title "Old Hogan's Goat". You'll probably find it on some lyrics-link blue clicky thing that deals with children's songs, camp songs, etc, if not on DT. The words are in I went to the animal fair, a book of animal poems edited by William Cole (1958), and (I think) in the Silly Songbook edited by Esther L. Nelson (1981). The tune is also used for "Sipping cider through a straw".
