Recently there was a post here announcing the deaths of the two leads from the series, Ed Bishop & Michael Billington, who both died within a week or each other. Having spent most of the month watching hours of these guys, the news effects me much more strongly now.

The score to UFO as with many Anderson projects was by Barry Gray. It's a mix of different styles: serious orchestra, easy-listening, jazzy organ riffs, and electronics. Kind of like Austin Powers in Space if you can picture it.

The Anderson fan club issued a soundtrack (now out of print) and there was a bootleg floating around too.

But for those without access to those discs, easy research finds that if you have the patience to listen to an M&E track, you can get a very good idea of what the UFO scores sound like here:

I just finished watching the UFO DVDs a couple and months back, and I was saddened too by the deaths of Michael Billington and Ed Bishop. I will always associate the show - and its music - with a particularly strong period of personal nostalgia. Colour TV was just becoming more easily available, though my parents couldn't yet afford one, so I used to go to a friend's house just to watch UFO every Saturday. The new experience of colour really added to my enjoyment of the show, plus it was being shown during one of those warm, blue-skied summers that seem to exist only in childhood memories.

In addition to the M&E tracks I linked to above, one should also check out these clips:

I thought it ran longer than one season?

I'd heard that there were more seasons planned but it was subsequently turned into SPACE:1999.

UFO is set in 1980 and the 2nd season was supposed to have a number of episodes about the aliens trying to destroy the moonbase. This became the germ of what would later become SPACE:1999.

If you want you can consider SPACE: 1999 a continuation of UFO though that is probably stretching it a bit.
