As Walt Disney World gears up for Epcot’s 35th anniversary on Sunday, October 1, Disney has brought back a retro video used to promote the new park in 1981.

The Dream Called EPCOT ran on a loop at the Epcot Preview Center in Magic Kingdom. The film offered a sneak peek at attraction models and renderings for Spaceship Earth, Horizons, The Living Seas, World of Motion, and CommuniCore. It also provided a first-listen to music composed for the park, like “It’s Fun to Be Free,” “Listen to the Land,” and “Universe of Energy.”

See the full vintage video below.
