Music Question About This Film...(Peter Thomas?)

I've been looking for a long time for the music played during the training scene of Chuck Barris, where he shoots communist figures and learns how to interrogate torturing. If you have any idea about the title of this song or the composer, please post it. The fact is that this film includes many good songs and music tracks but only a few of them are included in the soundtrack cd which i bought of course...If i'm right, i think that many of the music tracks played in this movie are composed by Peter Thomas a german composer of 60's cult movies... I thought the music i was looking for was his but after several tries i did not match the melody i am seeking with a certain title... Moreover, If you know any other titles of songs or tracks which are not included in the official soundtrack list, please let me know. For example, another pleasant music is heard while Chuck Barris is trapped and hit in a dead end during one of his missions in Germany (if you have seen the movie more than once, you'll probably know the scene i'm talking about). Thank you in advance for your kindness to correspond to my post...
