Main Street Electrical Parade
On Monday October 25, 1971; the Electrical Water Pageant premiered on the Seven Seas Lagoon and Bay Lake for "Dedication Day" at Walt Disney World. In addition to the 14 floats, its opening night included fireworks and pyrotechnics launched from the 14 floats and an additional float behind the Electrical Water Pageant. All of this was filmed by Walt Disney Productions and edited down for inclusion into The Wonderful World of Disney's Episode: "The Grand Opening of Walt Disney World", which aired on NBC on Friday October 29, 1971. The Paul Beaver version of Gershon Kingsley &amp; Jean-Jacques Perrey's "Baroque Hoedown", created specially for the Electrical Water Pageant, was used from 1971 until 1977. The original Main Street Electrical Parade at Disneyland used the same soundtrack from 1972 until 1974. In 1977, the premiers of the updated version of the Disneyland Main Street Electrical Parade and new (but similar) Walt Disney World Main Street Electrical Parade used a new version of "Baroque Hoedown" updated by Don Dorsey.
