That's interesting about the demand for major last-minute changes. I wonder if things would have been different if the rules had been the same as in the '60s. When Bob Justman didn't like a composer's cue on Star Trek, he went back and replaced it with a library cue or a cue from earlier in the season. By the time of ST: The Next Generation, that technique was not permitted, so if the producers didn't like a cue, they had to have the composer replace it with a new one. Given the timeframe for television series, that would not have left much leeway for the second compositions.
