Missing tracks from "The Tenant (Le Locataire)" OST

Hi,

I run a record label and I've been trying for some time to try and indentify and source some music from the film "The Tenant" by Roman Polanski. The score is by Philippe Sarde and has been released on CD (along with "Tess") but it does not include a couple of tracks played during a party / dance sequence in the movie (You can hear it here: http://www.youtube.com/watch?v=rXooKmjPUMQ ). The music in this scene is a jazzier/funkier version of the main Sarde theme...evey lead I've followed is a blank...
Any help or pointers would be hugely appreciated..
Thanks,
Mark
