The Muppet Alphabet Album

The Muppet Alphabet Album is an educational album based on the children's television series Sesame Street. It was first released in 1971 by Columbia, then reissued in 1976. Afterwards, it was reissued by Golden Music in 1990, followed by Sony Wonder in 1996, and by Koch Records in 2008. The latest reissues rename the album to Sing the Alphabet, and include Elmo singing a rendition of the song "ABC-DEF-GHI" in place of the original opening. The album features one song or sketch for each letter in the alphabet, performed by a variety of Sesame Street characters from the time. Each of the songs utilizes a different musical style.

Jim Henson, one of the album's producers, included a short description of the project on the album jacket of the initial release: "The idea is very simple – a little song or skit about each of the twenty-six letters of the alphabet..". A short history of the production process was later posted to a posthumous blog representing his estate.

For the third season of Sesame Street, multiple tracks from the album were adapted as segments for the show, with the Muppet characters lip-syncing to the original audio.
