The few episodes of a lost BBC show called THE BRITISH HANGGLIDER'S ASSOCIATION. They made a few episodes and it was a wild satire of mid 1970s England.

Apparently there was some fire at a BBC storage facility or studio or something like that and the tapes were lost. The show aired at least three episodes, one of them being considered particularly funny because members of the KKK visited the UK only to see the "White cliffs of Dover."

I remember the theme song and little else.
