Crude garbage collector Gus is horrified that the dating service has matched him with a prim college educated woman, and one who is taller than he is.

Floyd makes it to the club in time for the Commodores to play, but before they go on, Nicole sneaks up on stage and scores a huge triumph singing "Last Dance".

"[6] Vincent Canby of The New York Times wrote that the film was "really a record album with live-action liner notes featuring a dozen young actors, most of whom are quite nice and, as yet, unknown, and a few who are better known but not as impressive as the new people."

"[7] Arthur D. Murphy of Variety wrote, "Donna Summer makes her film debut in a comparatively charming role of an aspiring singer who cons her way to the disco stage and instant stardom.

Rest of cast, however, includes many with strong prior credits who are shot down by the Barry Armyran Bernstein script and Robert Klane's direction.

"[8] Kevin Thomas of the Los Angeles Times described the film as a "lively, zany, often crass, sometimes irresponsible but surpassingly good-natured movie," with Summer possessing "an exciting screen presence", if not strong acting abilities.

[9] Gary Arnold of The Washington Post panned the film as "90 aimless, alienating minutes" full of "TV sitcom-pilot boors, half-wits and low-lifes" who "don't sustain a glimmer of human interest.

He wrote that it is "perhaps the worst film ever to have won some kind of Academy Award", for Summer's hit song "Last Dance".

The film contains many popular disco songs, with many key performers featured, including Donna Summer, Pattie Brooks, Love & Kisses, The Commodores.

[19] Several songs heard in the film were not included on the soundtrack album, including Alec R. Costandinos' "Romeo and Juliet", Giorgio Moroder's "From Here to Eternity", The Originals' "Down to Love Town", D.C. LaRue's "You Can Always Tell a Lady (By the Company She Keeps)", The Commodores' "Brick House", The 5th Dimension's "You Are The Reason (I Feel Like Dancing)", Meco's "Meco's Theme" and the Village People tracks, "In Hollywood (Everybody Is A Star)" and "I Am What I Am".

The song was written by Paul Jabara, who the following year composed Summer's duet with Barbra Streisand, "No More Tears (Enough Is Enough)".

A digitally remastered version of the full soundtrack on a 2 disc set was released on PolyGram Records on March 25, 1997.

It was released as a single in certain territories and has since been remixed and re-edited a number of times for inclusion on various hits packages issued by Motown/Universal Music.

The final part of Donna Summer's "Last Dance" is later re-included as a separate track titled "Reprise" toward the end of the soundtrack album.
