As for the lost or destroyed soundtrack from the recording session, it strikes me as uncharacteristically sloppy on the part of the production companies ("Moonraker" was a joint production between Eon and Les Productions Artistes Associes) to let such elements slip away. You start with the recording session, then the music editor uses a copy of the tracks to cut them into the production, then there's the final mix where certain levels are tweaked accordingly. And all this is lost??
Wow.

In more cases than not, especially scores from the past. Recording sessions were thrown away, leaving only the soundtrack masters [in those days LP soundtracks] preserved. I think score collectors here will note probably the most famous case of a score being missplaced, which would be Jerry Goldsmiths fantastic score for Legend. The original scrips, original scoring sessions were lost. Only a 2 Track DAT tape exisits [after the audio mixer decided to keep it following studio reqrests to trash the masters] for which the terrific CD was pressed.
Sorry Just Doesn't Cut It, but its the way it is.
Scoring Session status on Bond films [not confirmed]
Dr. No - LOST
From Russia With Love - LOST
Moonraker - LOST
A View To A Kill - LOST
That is roughly what I could piece together from Lukas Kendal before he pretty much said he was tired of Bond music questions [which is why I think someone else should have done the project]
While the expanded versions are terrific, there is NO excuse why the rest of the scores could not get expanded. If it takes time to do Spy Who Loved Me or Octopussy, then DO IT. The remastered soundtracks, while impressive are still a half-assed job.
FUTURE.
The New MGM-DVD's. Interesting enought the early films will be mixed from Mono 1.0 to 5.1 mix. In order to do a 5.1 mix, i would assume they need...
Music Steams
Dialogue Streams
Sound Effects
Other Misc Streams
well, if they have those, especially for like say Dr. No, then that is a good sign that they have found the music streams and are using them. So hopefully they will then use those same streams for a future expanded CD. Unless these "GLORIOUS" 5.1 mix's will be just like the other remixed Bond films that really offer crappy 5.1 surround sound.
