I am a trekkie (trekker being a later politically correct term I have never liked!) from the time of the original series. How come no one has mentioned The Devil in the Dark? - "Damn it Jim, I'm a doctor - not a bricklayer!"

I never watched the other series with much regularity. But I absolutely loved "Inner Light" (I read on a Compuserve forum that the music was a variant of Skye Boat Song") And there was an episode that ended with Patrick Stewart singing Minstrel Boy... There's the folk connection!

Been a sci-fi reader even longer. Started with Edgar Rice Burroughs (not when he originally published, thank you) Van Vogt, Simak, Zelazny. I don't read much now in the genre (C. S. Friedman and Feist being the exceptions) - I think it's deteriorated. Of course a lot of people disagree - if sci-fi readers were morris dancers that line might start a fight in a bar!
