Besides performers John Travolta and Olivia Newton-John, the album also featured songs by rock and roll revival group Sha Na Na as well as the hit song "Grease", a tune written by Barry Gibb (of the Bee Gees) and sung by Frankie Valli (of The Four Seasons) that was an additional U.S. No.

[citation needed] The cover gives credit to, and prominently features, the two stars of the film—John Travolta and Olivia Newton-John—although they only appear on seven of the 24 tracks.

Songs in the musical that were not performed by Rizzo, Danny, Sandy, the Teen Angel, or Johnny Casino & the Gamblers were given to those characters or to St. Louis and Bullens; these included Sandy's original feature number "It's Raining on Prom Night" (given to Bullens and used as a jukebox background song), Marty's "Freddy, My Love" (given to Bullens), Doody's "Those Magic Changes" (given to Johnny Casino & the Gamblers), Kenickie's "Greased Lightnin'" (given to Danny), and both of the songs originally attributed to a character named Roger that was written out of the film, "Mooning" and "Rock'n'Roll Party Queen" (both given to St. Louis; "Mooning" was replaced in function in the film by the 1930s standard "Blue Moon," performed by the Gamblers).

[5] In the UK, the album proved even more successful where "You're the One That I Want" and "Summer Nights" (a song carried over from the original musical) reached No.1 for nine and seven weeks respectively, while "Grease", "Hopelessly Devoted to You" and "Sandy" all became top three hits.

One of these, David Hungate, also performed on Newton-John's album Totally Hot with Toto guitarist Steve Lukather.

Other musicians on the soundtrack had previously worked with Elton John, Steely Dan, Bee Gees and others.[when?]

[12][13] In their review, Billboard stated that "RSO follows its record breaking Saturday Night Fever soundtrack with another apparent smash film track.

With great vocals from stars Olivia Newton-John and John Travolta and help from Sha-Na-Na, Frankie Valli and Peter Frampton, this 2- LP set should slide to the top of the pop chart.

In April 1991 it was released through Polydor Records as a single disc replicating the sequence of the original 1978 RSO LP.
