I'd appreciate it if someone could compile a list of all the cues here that weren't used onscreen. I hadn't realized there were unused cues in "The Man Trap."
For Man Trap, there were portions of cues unused. In "Conference," all but the last few seconds as Kirk runs to the "dispensery." Also, "Lazer Dazer" the the music is dialed out as Kirk does his crawl through the sand. There are some more in there that popped up in later episodes, IIRC. Like when Crater runs off and Kirk, mcCoy look for him. A lot of that was dialed out, but I remember hearing the opening of that cue in A Taste of Armageddon and even later in Gamesters of Triskelion when Kirk gets his plan to wager for his freedom.
I'd have to go through the whole set again top compile something detailed, but Catspaw had some fly by cues dropped, probably because they sounded too much like the approach of covered wagons. The finale cue was probably too upbeat as well.
