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 and Walt Disney World, and a replacement was sought for the original song, "There's a Great Big Beautiful Tomorrow" (also by the Sherman Brothers).

"There's a Great Big Beautiful Tomorrow" was reintroduced to the revamped pavilion in 1994 during Tomorrowland's transition into "The Future that Never Was." An instrumental version of "The Best Time of Your Life" is currently part of the background music loop for Tomorrowland at Disneyland, the Magic Kingdom, and Tokyo Disneyland.

The song was written by Richard and Robert Sherman for the Carousel of Progress, one of four attractions Walt Disney and his Imagineers developed for the 1964 New York World's Fair. "There's a Great Big Beautiful Tomorrow" premiered with the show. The attraction moved to Disneyland after the fair. In 1973, the Carousel of Progress closed and moved to the Magic Kingdom at Walt Disney World.

The attraction was given a new show during the move, to update an increasingly outdated view of the future. General Electric, the sponsor of the Carousel of Progress, commissioned a new theme song, one to focus more on the here-and-now than on tomorrow, and the Sherman Brothers penned "The Best Time of Your Life]. It was sung by Andrew Duggan, who also narrated and voiced the main character in the show. The song stayed with the show through another update in 1981, and General Electric's dropping of sponsorship in 1986.
