Giorgio Moroder's instrumental track "Night Drive", another variation on the "Man Machine"/"Call Me" theme, was also issued as a single in certain territories.

The song "Love and Passion" was written by director Paul Schrader and Moroder and was performed by Cheryl Barnes, and can be heard in the movie in the gay nightclub scene (filmed at Los Angeles gay club The Probe, which opened in 1978) where Gere's character Julian goes to find Leon, his pimp.

The Giorgio Moroder instrumental "The Seduction (Love Theme)" was also recorded by German bandleader James Last as a saxophone tune featuring David Sanborn (uncredited).

American Gigolo was one of two soundtrack albums to be written and produced by Moroder in 1980, the other being Foxes, which included Donna Summer's hit single "On the Radio" as well as tracks by Janis Ian and Cher.

At the same ceremony, Donna Summer's "Last Dance", produced by Moroder from the soundtrack to Thank God It's Friday, won an Academy Award for best song (as well as a Golden Globe).
