What is the song they play at the when Epcot is about to close?

The Macarana. They play it to symbolize Mexico for when it first opened. Horizons was closed, because people thought that Epcot was boring; Their rides weren't fast enough. Same with the other slow rides. That's why they have Test Track, and MISSION:Space. They Can't take down Spaceship Earth because it is the symbol of Epcot.
