The Brain Eaters

I read your post re: The Brain Eaters. I have done extensive research on the music and have also come to the conclusion that there never was a Tom Jonson. I have identified much of the score but the piece that eludes me is the Main Title. Does anyone have any idea what that's from? Your help would be greatly appreciated. It's driving me crazy.

In the meantime , this is a fun film (if derivative). The biggest mistake might be the Pipe Cleaner antennea on the little monsters. The idea the creatures are subterranian in nature was very different for the period. All in all a good fun romp. The classical score does add a weirdness that somehow compelling.
