there WAS a musical theme they used which I thought was one of the prettiest pieces of music I'd EVER heard in my, at THAT time, young life. It was used in the episode where those funky flowers shot spores at people,another one was in "Shore Leave"-Whenever Kirk mentioned "Ruth", , & when Sandoval mentioned "Leila Kolodny,Our Botanist".. I had a VERY bad case of 6th-7th grade LUST for this pretty tall blonde named Melissa... who, of course, barely knew I existed..Her daddy ran/owned the local bank, she was an only child, & yet was nowhere nearly as "Stuck on herself" as she should have been. Her daddy & mine were pretty close, Bob was a "Gentleman Farmer", as most everyone around here was. He was big in Hereford Cattle,my dad's favorites were Black Angus. Angus cattle weren't bothered by a lot of the problems Hereford cattle were, one of the main troubles being horns. Angus don't have them.
