Um, it was Jerry Goldsmith's theme music. Alexander Courage's theme wasn't quoted until Trek2. If the movie had been the pilot as originally intended, it would have been an OK 2-parter. But as the $ piled in, the studio said "There is no way we will recoup our costs from this as a TV show," and had the project retooled as a feature movie. This caused several changes to be made. I still have my 1980 Trek Calendar with Kirk in a thruster suit next to Spock (scene was cut). Oh, and the Borg being the ones to reprogram V'Ger was originally a joke by some production staffer/writer when the Borg first appeared. As a joke, it worked. If you books actually adopted it... Well, I'd just say I'm sorry to hear it was taken seriously.
