"American Gigolo": alternative soundtrack?

Yestarday I was watching "American Gigolo" on DVD (RC2). I have seen this movie when it was shown in theatres over 20 years ago.
There is a scene (some 35 minutes into the movie) when Richard Gere is choosing his outfits from his wardrobe. I definitely remember that this scene was originally accompanied by a typical Giorgio Moroder synthesizer track which was very well fitting into the instrumental "Call Me" context, if I may say so.
Now, when I saw that scene yesterday, there was some Motown style track (maybe sung by Smokey Robinson). At that actual scene, I thought I was sitting in the wrong movie!
Do you know something about this very strange happening?
Peace
