Walt Disney's Carousel of Progress
Walt Disney's Carousel of Progress is an attraction located at the Magic Kingdom park at the Walt Disney World Resort.
 Created by both Walt Disney and WED Enterprises as the prime feature of the General Electric (GE) Pavilion for the 1964 New York World's Fair, the attraction was moved to Tomorrowland at Disneyland in Anaheim, California as Carousel of Progress, remaining there from 1967 until 1973.
 It was replaced in Disneyland by America Sings in 1974, and reopened in its present home in Walt Disney World Resort's Magic Kingdom in 1975.
There's a Great Big Beautiful Tomorrow
"There's a Great Big Beautiful Tomorrow" is the theme song to two Disney attractions, Walt Disney's Carousel of Progress at the Magic Kingdom of Walt Disney World (formerly at Disneyland) and Innoventions at Disneyland.
 It was also used in one scene of the Epcot attraction Horizons.
Iron Man 2 (soundtrack)
Iron Man 2 is a soundtrack album by Australian hard rock band AC/DC, released on April 19, 2010 as the soundtrack to the film of the same name.
 Iron Man 2: Original Motion Picture Score, a separate film score album for the film composed by John Debney was released on July 20, 2010.
 The track "Make Way for Tomorrow Today", used for the Stark Expo, was composed by Richard M. Sherman as an homage to his own "There's a Great Big Beautiful Tomorrow". Rail transport in Walt Disney Parks and Resorts
Rail transport can be found in every theme park resort property owned or licensed by Walt Disney Parks and Resorts, the theme park and vacation resort segment of the larger Walt Disney Company.
 The origins of Disney theme park rail transport can be traced back to Walt Disney himself and his personal fondness for railroads, who insisted that they be included in the first Disney park, the original Disneyland (a key component of the Disneyland Resort) in California in the United States, which opened on July 17, 1955.
 The Disney tradition of including transport by rail in its parks has since been extended to other Disney properties with the opening of Walt Disney World in Florida in the United States, Tokyo Disney Resort in Japan, Disneyland Paris in France, Hong Kong Disneyland Resort in China, and Shanghai Disney Resort in China. Disneyland Park (Paris)
Disneyland Park, originally Euro Disney, is a theme park found at Disneyland Paris in Marne-la-Vallée, France.
 The park opened on 12 April 1992 as the first of the two parks built at the resort.
 Designed and built by Walt Disney Imagineering, its layout and attractions are similar to Disneyland Park in Anaheim, California and Magic Kingdom at Walt Disney World in Bay Lake, Florida.
 Spanning 56.656 ha (the second largest Disney park based on the original, after Shanghai Disneyland Park), it is dedicated to fairy tales and Disney characters.
 In 2016, the park hosted approximately 8.4 million visitors, making it the most-visited theme park in Europe, and the 13th-most visited theme park in the world. Disneyland 10th Anniversary
"Disneyland 10th Anniversary" is a 1965 episode of "Walt Disney's Wonderful World of Color".
 It begins with Walt Disney showing viewers and Disneyland ambassador Julie Reihm plans for upcoming attractions, including It's a Small World, Pirates of the Caribbean and the Haunted Mansion.
 In Disneyland, the Disney characters celebrate Disneyland’s Tencennial, with a show in front of the Sleeping Beauty Castle and a parade put on by a local high school band and cheerleaders.
 Next, Walt Disney describes a brief history of the construction of the park, followed by a tour of some of the attractions at the time, including Matterhorn Bobsleds, Jungle Cruise, the Flying Saucers, the Mine Train Through Nature's Wonderland and the Walt Disney's Enchanted Tiki Room.
 The climax of the episode is a Dixieland band on the Mark Twain Riverboat, and some other boats on the Rivers of America put on an interesting water show. Disney Sing-Along Songs
Disney Sing-Along Songs is a series of videos, laserdiscs and DVDs with musical moments from various Disney films, TV shows and attractions.
 Lyrics for the songs are displayed on-screen with the Mickey Mouse icon as a "bouncing ball".
 Early releases open with a theme song introduction (written by Patrick DeRemer) containing footage featuring Professor Owl and his class, seen originally in 1953 in two Disney shorts, "Melody" and "Toot, Whistle, Plunk, and Boom" (voiced then by Bill Thompson).
 Professor Owl (now voiced by Corey Burton) hosts some of the videos, while either Ludwig Von Drake or Jiminy Cricket host others, and later volumes, as well as the two Christmas videos, had no host at all.
 The footage of Von Drake and Jiminy Cricket were taken from several television programs (including the Walt Disney anthology television series, and "Mickey Mouse Club") featuring the characters in the 1950s and 1960s. Horizons (Epcot)
Horizons was the name of a dark ride attraction at Epcot (then known as EPCOT Center), a theme park at Walt Disney World in Bay Lake, Florida.
 Located on the eastern side of the "Future World" section of Epcot, the attraction used Disney's Omnimover conveyance system, which took guests past show scenes depicting visions of the future.
 It is believed to be the sequel to Walt Disney's Carousel of Progress, an attraction in Tomorrowland at Walt Disney World's Magic Kingdom.
 Horizons was the only attraction in "Future World" to showcase all of Epcot's "Future World" elements: communication, community interaction, energy, transportation, anatomy, physiology, along with man's relationship to the sea, land, air, and space.
 The attraction officially opened on October 1, 1983, as part of Phase II of Epcot.
 Horizons originally closed in December 1994, a little more than a year after General Electric had ended its sponsorship of the attraction.
 Horizons re-opened in December 1995 due to the closure of two other attractions that were down for refurbishment in "Future World", Universe of Energy and World of Motion.
 The attraction permanently closed on January 9, 1999, after which the attraction was dismantled and its structure demolished to make room for , a motion simulator thrill ride that opened on October 9, 2003. The Best Time of Your Life
"The Best Time of Your Life" (often mistakenly; "Now Is The Time", the first lyric) is a song written by Richard M. Sherman and Robert B. Sherman in 1974 as a new theme song for Walt Disney's Carousel of Progress.
 The attraction was being moved from Disneyland to Walt Disney World, and a replacement was sought for the original song, "There's a Great Big Beautiful Tomorrow" (also by the Sherman Brothers). Walt Disney World Explorer
Walt Disney World Explorer is a point and click Windows application, released on CD-ROM by Disney Interactive in 1996.
 The application focuses on the Walt Disney World Resort near Orlando, Florida, and consists of virtual tours, trivia and slideshows of the resort's parks, attractions and hotels.
 Various minigames are also built into the application, such as a quiz that allows users to test their knowledge of the resort, and a game which involves finding Hidden Mickeys.
 About two years after it was released, a "Second Edition" was made with then-new and updated information, such as Disney's Animal Kingdom and Disney's Coronado Springs Resort.
 The application is narrated by Hettie Lynne Hurtes and Corey Burton, the latter of which is a veteran voice actor who has been featured in several Disney attractions.
