"The Rainbow Connection" is a popular song written by Paul Williams an Kenneth Ascher and originally performed by Kermit the Frog (Jim Henson) in The Muppet Movie in 1979. By extension, as evidenced in the TV special, The Muppets at Walt Disney World, the song has come to epitomize the ideals and artistic spirit of Henson and his company as much as "When You Wish Upon a Star" represents Walt Disney and his company.
