America Sings opened on June 29, 1974, replacing the General Electric-sponsored Carousel of Progress attraction, which had moved to the Magic Kingdom at the Walt Disney World Resort in 1973. America Sings used the same Carousel Theater as its predecessor. The building had an outer ring of six theaters, connected by divider walls, that revolved mechanically about every four minutes around the six fixed stages in the center of the building.
Unlike Disneyland's Carousel of Progress, which rotated clockwise, America Sings rotated in a counter-clockwise direction. Also, unlike Carousel of Progress, America Sings only used the lower level of the Carousel Theater. The upper level was eventually used to house the SuperSpeed Tunnel in 1977 (which later became the Game Grid of Tron) that the PeopleMover transportation attraction passed through.
