I managed to see this 1975 spy movie recently and was really taken by the score by Richard Rodney Bennett. It was so unlike his usual style such as Lady Caroline Lamb and such that i found it hard to believe he was the composer. A very mid seventies style thriller score that I would love see released. It was a Warner movie so maybe the tapes are languishing in some vault. I always liked his Billion Dollar Brain score but this is very very different.
