'Jazz it Up' is probably my favourite cue on The Marseilles Contract. It's a score I didn't appreciate for a long time but I do more now. I especially love the percussion (tablas!) which is very prominent in most tracks.
Chris Karan was Roy's drummer and percussionist on nearly all these scores.
This was discussed briefly in another thread on this board not long ago. The consensus is that Paul Fishman did some fiddling and remixing on some of these albums, because if you watch the films themselves, nothing like these tracks appear. And certainly not that one in THE MARSEILLE CONTRACT...
