Early versions

The earliest version of the song was recorded by the Hues Corporation in 1974, for their second studio album Rockin' Soul. The song was performed by the original Baltimore cast of The Wiz at the Morris A. Mechanic Theatre in October 1974 which included Renee Harris as Dorothy, Charles Valentino as the Scarecrow, Ben Harney as the Tin Man, Ken Prymus as the Cowardly Lion, and Butterfly McQueen as the Queen of the Field Mice.^[2] From January 5, 1975, the song was performed by the new Broadway cast at the Majestic Theatre which included Stephanie Mills (Dorothy), Hinton Battle (Scarecrow), Tiger Haynes (Tin Man) and Ted Ross (Cowardly Lion), who also performed the song on the original 1975 cast album for The Wiz. The song was a number-one disco hit for five non-consecutive weeks in a recording by the disco studio group Consumer Rapport. Produced by Stephen Y. Scheaffer and The Wiz musical arranger Harold Wheeler,^[3] the Consumer Rapport version hit the Billboard Soul Singles chart, peaking at #19 and the Hot 100, peaking at #42.^[4]

Diana Ross and Michael Jackson version

In 1977, "Ease on Down the Road" was recorded as a duet between Diana Ross and Michael Jackson and released as the theme song of the 1978 film adaptation of The Wiz. As with the rest of the music in the film, the film version of "Ease on Down the Road" was produced by Quincy Jones. The recording was one of Jackson's first collaborations with Quincy Jones, who became his main producer during the late 1970s and 1980s.

Released as a single by MCA Records in late summer 1978, the song missed the U.S. top 40 by one position, peaking at #41 on the Billboard Hot 100. It reached #17 on the Billboard Hot Soul Singles chart the same year. AllMusic's William Ruhlmann wrote that duet between Jackson and Ross has "spectacular vocal firepower" and that it outperforms the 1975 version by Consumer Rapport.^[5] The recording also earned Jackson his first Grammy Award nomination with Ross (his previous two were with his family group, the Jacksons) in the category of Best R&B Performance by a Duo or Group with Vocal in 1979.

In 1980, Jackson was a guest on Kraft Salutes Disneyland's 25th Anniversary and, along with Disney characters (Mickey Mouse, The Seven Dwarves, Donald Duck, Pinocchio, Minnie Mouse, Chip 'n' Dale, Pluto, Winnie the Pooh, The Three Little Pigs, and Goofy), performed the song in a medley with the Disney signature song "When You Wish Upon a Star".
