This song also appears in the musical, but it was changed to fit the story of Neleus from Mary Poppins Opens the Door. Also added to it was that Mary makes the park colorful and glamorous compared to the usual park that the Banks children go to often. It also shows that the kids were not won over by Mary Poppins at first and it wasn't until Neleus came to life and the park changed before they were amazed.("Boring, just like other nannies, thinking parks are good for us. It's just statues, ducks and grannies. I don't understand all the fuss..." - lyrics from the musical version)
This song has been parodied in Forbidden Broadway Cleans Up Its Act and the show's album, with the name "Jolly Holiday with Rudy," which made fun of the cleaning of Broadway at the time.
