The Challenge is an interesting case, cos there never was an LP at the time of the films’ release.
Now I’m sure if there had been, Goldsmith would have fashioned a cool 35-40 minute album ala Capricorn One, Outland and The Swarm etc.
But having recorded the music off the film, back in the day, to get to hear the music multiple times, The Challenge (like many scores from that period) didn’t have a duff track within it.
So I was unwilling to sacrifice ANY music from the film, when it was finally released (on CD).
I know a lot of latter day scores feature far too much ‘filler’ music and deserve a good whittle, but many of the great scores of the 60s, 70s & 80s are required listening in complete form.
