Theme Tune from 70's cult TV show "UFO"

One of my all-time favorite groovy theme-tunes from TV. Remember the aliens that could only breathe the liquid substance in their helmets? Or the 60's haircuts? The miniskirts? That's gotta be a memorable, cult TV series if there ever was one. Even the effects weren't too bad considering the period in question. Click here to check out the psychedelic tune.
