There used to be a sci-fi themed bar in Westminster, London called Page's Bar and every Saturday night they played fan made music videos edited together from footage of various sci-fi shows, mostly Star Trek and Babylon 5. The videos were uploaded to YouTube after the bar closed and these are some of the best ones:
Star Trek: I Will Survive
Star Trek: Too Sexy For My Shirt
Babylon 5: Glory Days
This is the one that you have to watch if you don't already know it. It's by far the best and absolutely hilarious if you're a sci-fi fan:
