I was watching Conscience of the King, and noticed the Star Trek theme playing at the party. I think it was heard in the bar in Court Martial, too. Is that a "current" hit, or is it what we would call elevator music? Either way, it's a charming period touch that probably would have elicited guffaws if it were tried on The Next Generation. Are Uhura's songs popular "crowd pleasers" or are they original works? For that matter, would there even be such a thing as popular music in this time period?
