QMTV for Schools and Colleges

On catching a glimpse of Saxondale last night, I instantly recognised the theme tune ('House of the King' by Focus, apparently) as being the very same as that of a classic schools language programme. As did one or two others on t'interweb, it seems.

But which one?

[Poll #767090]

Whilst on the subject of theme tunes, can anyone think of any other examples which were album tracks or singles before being used as a theme tune? I know there are a plethora of folk/prog and Radiophonic/electronic tracks which have been plundered by both the BBC and ITV for their educational broadcasts in the 1970s and 1980s, and a list of both tracks and artists would be a useful resource for this humble little community.

Any suggestions?
