He also appeared in Schlesinger's 1975 film The Day of the Locust, where he sang a cover of the Marlene Dietrich song "Hot Voo-Doo" in drag.

In 1981, Jabara starred in another John Schlesinger film, the comedy Honky Tonk Freeway, as truck driver/songwriter T. J. Tupus, hauling lions and a rhino.

No recording was made of the score, which featured both Jabara's trademark disco music and traditional Broadway-style numbers.

[5] In 1976, Jabara contributed a song to the 20th Century Fox motion picture sound track of Mother, Jugs & Speed, starring Bill Cosby, Raquel Welch and Harvey Keitel.

Jabara's solo albums on the disco label Casablanca Records include three duets with Donna Summer: "Shut Out" (1977), "Something's Missing (In My Life)" (1978) and "Never Lose Your Sense of Humor" (1979).

[4] In 1982, Two Tons O' Fun, renaming themselves as the Weather Girls, agreed to record his song "It's Raining Men", previously rejected by Summer, Streisand, Cher and Ross.

Other songs Jabara had covered by major artists include "Hope" by Billy Preston (1981), "Two Lovers" by Julio Iglesias (1984)[4] and "This Girl's Back in Town" by Raquel Welch (1987).

In 1986, Jabara released his final album, the concept musical De La Noche: The True Story – A Poperetta, featuring guest vocals from Leata Galloway, Diva Gray and Pattie Brooks.

It was a musical assembled from Jabara's well known disco songs and told the story of a modern-day teenager who goes back in time to spend one night at Studio 54.
