The Pike epsiodes weren't the first TOS stuff I had seen but there is the later episode where they return him to the plenet because they can give him a better life. I actually think I saw that one first and then made a point of checking out the pilot. If I'm not mistaken, there is a reference in one of the TNG era series to a Christopher Pike medal or was that in one of the TOS movies? You all know your Sci-Fi much better than I do!
I've never seen the original pilot outside the two-part episode it wa made into, but I've read a book or two with Pike in the hot seat. Was funny to run trough my mind, "Wait, he's Christopher Pike?" then to only laugh at myself when I was told I just met Kirk.
I believe I found it through a torrent but wouldn't be surprised if you could find it on YouTube. It's in black and white and there was some comentary from Gene to kick it off and in closing. I'm honestly tempted to try and dig it up again because it has been quite some time since I've seen it.
