Where can I get the soundtrack to Wag The Dog?

I really enjoyed watching the 1997 picture Wag the Dog, but I found the music even better. Polygram released a soundtrack CD´, but some of the film’s best scores, such as the Green Beret ripoff about the men of the 303 are missing. Are there any supplementary CDs planned to come out, or have those scores been released on music download services, or aren’t they available at all? Personally, I think those were lenghts better than some of the ones that have made it onto the CD.
