What are the words to the song The Jitterbug from The Wizard of Oz?

According to Aljean Harmetz in his book The Making of The Wizard of Oz, "The Jitterbug" was an artifact left over from premises made in early drafts of the script. The original producers thought that a 1939 audience was too sophisticated to accept Oz as a straight-ahead fantasy; that was why it was reconceived as a lengthy, elaborate dream. Because of a perceived need to attract a youthful audience through appealing to modern fads and styles, the script originally featured Dorothy's journey as a series of musical contests. A spoiled, selfish princess in Oz (part written for Deanna Durbin) had outlawed all forms of music except classical and operetta, and went up against Dorothy in a singing contest in which Dorothy's jitterbug style enchanted listeners and won the grand prize. The only remnant of this contrivance was "The Jitterbug."
