Going on from Smalltalks question 2 threads down, it reminded me of a programme that used Jean Michel Jarre's, Oxygen as a theme tune. I can't remember what the programme was though. Though it might have been World in Action but I checked that on youtube and it wasn't that.
Was it Equinox. It was a long-running Channel 4 popular science and documentary programme. The series ran from 1986 to 2001, originally airing on a weekly basis.
Answered variously around the web as 'Tomorrow's World' (although I don't remember it being used for that), Yorkshire Television's "Where's There's Life" (networked on Wednesdays at 7.00pm, featuring Miriam Stoppard and Rob Buckman, presenting items on science and medicine) and "Space: 1999" (but I've got me doubts about that one too).
"Where There's Life" would seem to be the most likely contender as the correct answer to your question.
I've had a look at that with filters for News, Documentaries and Educational in both the 70s and 80s but it doesn't seem to be coming up with anything other than Question Time.
The programme you're looking for was called "Where There's Life" with Miriam Stoppard and the slightly over enthusiastic Rob Buckman. It used a version of Jarre's Oxygen 4 - but it's NOT the album version and is probably an 80's remix by somebody who remains obscure. It can be heard in the background of this Canadian Promo from the early 80's.
