UFO — opening theme

UFO — closing credits

UFO was a British television science fiction series created by Gerry Anderson and Sylvia Anderson and produced by the Anderson's and Lew Grade's Century 21 Productions for Grade's ITC Entertainment company. The Andersons had previously made a number of very successful marionette-based children's science fiction series including Stingray, Thunderbirds, and Captain Scarlet. They had also made one live-action science fiction movie, Doppelgänger, also known as Journey to the Far Side of the Sun, and now felt ready to move into live-action television and aim at a more adult market.

UFO was the Andersons' first totally live-action TV series. Despite the assumption of many TV station executives, the series was not aimed at children, but deliberately sought an older audience; many episodes featured adult themes such as adultery, divorce, and drug use.

UFO first aired in the UK in 1970 and in US syndication over the next two years. In all, 26 episodes, including the pilot, were filmed over the course of more than a year, with a five-month production break caused by the ultimate closure of the MGM-British Studios in Borehamwood, where the show was initially made.

The show's basic premise is that in the near future –a fictional version of 1980 (a date indicated in the opening credits) – human beings are being covertly harvested for their organs by aliens.
