Changes

Although the Edison Square concept never saw the dawn of day, General Electric was still interested in partnering with Disney. They approached Walt, and asked him to create an attraction for the 1964 World's Fair in New York. Walt reached back to his old idea, and once again pitched General Electric on the idea of an electrical progress show. GE loved the idea, and agreed to sponsor the new attraction <ref> http://blog.silive.com/goofy_about_disney/2015/01/disney_goes_to_the_fair_carousel_of_progress_saw_a_number_of_firsts_outside_the_ge_pavilion.html </ref>.

A big advancement in the development of the General Electric attraction was the fact that WED Engineers finished the Audio Animatronic technology that they had been working on. Although the new technology was not yet perfect, it was good enough to start creating a show, which would eventually become the Carousel of Progress. Imagineers, including Disney legends Roger E. Broggie and Bob Gurr also devised what they called a "Carousel Theater", a theater which actually rotated clockwise allowing guests to move on to the next scene without having to stand up <ref> http://modernmouseradio.com/2012/04/19/its-a-great-big-beautiful-tomorrow/ </ref>.

Since there would be a time lapse between when one scene ended and another started, Walt asked the Sherman Brothers to write a song that would bridge the scenes together. Walt was so excited about the show when he told them about it, his enthusiasm stuck with the Sherman Brothers as they worked on the song. The song that the brothers composed was an upbeat and optimistic song about the bright future on the horizon titled [["It's A Great Big Beautiful Tomorrow"]]. The Sherman Brothers later remarked, that they felt "It's A Great Big Beautiful Tomorrow" was like Walt's theme song because it featured the same kind of optimism about the future that he had <ref> http://www.thedisneyproject.com/2013/03/theres-great-big-beautiful-tomorrow.html </ref>.
