An excellent review. Best Years is one of my all-time favourite films. It never fails to elicit various emotions on my part. I should note, furthermore, that I produced the only modern recording to date of Hugo Friedhofer's Oscar-winning original score. That was in in 1978. Friedhofer's score presently ranks sixth in the 100 Greatest Film Scores of All Time poll conducted by the American Film Institute a few years ago.
Incidentally, in 1978, when I visited Goldwyn Pictures to organise the production of the recording, the late Tom Bodley informed me that a Perspecta-encoded soundtrack had been prepared by the Goldwyn sound department for reels 1 and 2. The soundtrack which included 3-channels was recorded on a separate 35mm optical film, which was interlocked with the film. I included this material on the Entr'acte LP release.
The laserdisc features the Perspecta re-mix (if I might call it such), but all of the other releases do not feature Friedhofer's music-and-effects track.
