BBC television show name wanted

I'm looking for the name of a BBC show from the 1980's. It was an interesting show and had a nerdy host who would explain how everyday items worked. He also had a bearded partner who would help him with demonstrations. It was kind of a combination of educational stuff combined with Mythbusters. It seemed like they were headquartered at a junk yard of some time. The only distinctive thing I remember was that the opening song was a raga version of Take Five by Dave Brubeck. Any help is appreciated.
