On the trailer, there's a really cool version of "Call Me". It must be Moroder, but I can't find it anywhere to download and realllllly want it. Help!

I don't recall which version they used in the theatrical trailer, exactly, but if you have a look around the torrent sites for a file compilation called "Blondie: The Essential CDiscography, 1975-1982), it's a veritable goldmine of AMERICAN GIGOLO cues. In addition to multiple versions of tracks like "Night Drive" and "Palm Springs Drive", there are six, count 'em, six different mixes of "Call Me"---including the "soundtrack version" which opens the picture, and which I spent years searching high and low for. There are also three years-later remixes done by other parties, and two Spanish mixes (!). I would imagine that whichever version you are looking for, it's in there somewhere.
Good luck!
