I think Grandstand used to have a good theme tune, I liked it as a kid, can't remember it now though!
Also the snooker theme tune when it was nice and simple and played on an electric guitar. They've ponced it up now though.
And the theme tune from QI's very jolly.
"every nation ... has a tv station ... " bla bla bla
any one remember this lyric from an 80s chilren's bbc programme? The tune is still in my head, although any memories of the actual programme have faded. I'm just left with that snippet. It does my nut in.
