SPOILERS! All these music clips should've been put in SPOILERS! SPOILERS I SAY! The movie is ruined for me, now!
But seriously, folks, I'm becoming a sentimental old fool. The clips above with the Alexander Courage theme made my eyes well up a little.
Edited to add: I just wish Spock could come along, lay hands on me, and get those damn Roddenberry lyrics out of my head. "Beyond the rim of starlight, my love is wandering in starflight...."
Really, I'd have a lobotomy just to forget those words and be able to enjoy the theme without them crossing my mind.
