There’s a Great Big Beautiful Tomorrow “Shining at the end of every day,” which is how the song, written by Richard M. Sherman and Robert B. Sherman, began. It was written for the G.E. Carousel of Progress built by Disney at the 1964-1965 New York World’s Fair, and it followed the attraction when it moved to Disneyland. Due to a change in corporate philosophy at General Electric, however, the song was dropped when the attraction moved to Magic Kingdom Park at Walt Disney World in 1975. Instead, a new song, “The Best Time of Your Life” was commissioned. But by then, the original song was a favorite among many park goers, and its return in November 1993, marked a historic moment for those who recalled the original show.
