"At the Zoo" was one of Simon & Garfunkel's single releases in 1967. The song is one of Paul Simon's many tributes to his hometown of New York City, and was written for the soundtrack of The Graduate, specifically the scene which takes place at the San Francisco Zoo. However, the song was not used in the film. The song begins with Simon's short lyrical introduction in the key of A Major, but it soon transitions to the key of G Major, being a whole step down from the beginning. The narrative tells the story of a trip to the Central Park Zoo; when the singer reaches the zoo, he anthropomorphizes the animals in various amusing ways. The song was licensed in advertisements for the Bronx Zoo, the San Francisco Zoo and the Oregon Zoo in the late 1970s.
