It was once believed that Sullivan had re-used the music of "The Zoo" in his later compositions. In 1927, Herbert Sullivan and Newman Flower wrote, "The "Zoo" was a trifle composed by Sullivan in 1875. ... It was never printed, and much of the music was used up again by the composer in his later Savoy operas." This statement turned out to be one of many misleading statements in Sullivan and Flower's book when the score of "The Zoo" was rediscovered. No re-use of music from "The Zoo" has been identified.
