Help - what's this theme tune

Hi,
I've had this theme tune in my head for weeks now.
It sounds like it's a UK TV programme, probably 80s or 90s, perhaps quiz-related.
There are no words - just a theme, in four bars:

da da da da da da daa,
da da da da da dadada,
da da da da da da daa
dadada dadada, du du du dududu bong!

I think Chris Evans maybe plays it on his Radio 2 breakfast show.

Any help appreciated!!!

Cheers mate - that's a classic, but it's not quite the same as the one I've got in my head.

Any other thoughts anyone?

That's the one on Chris Evan's show ...
Click on the link:

then click on 'listen here' on the iplayer, go to 9mins.



I'll try again lol.......

He also plays the theme to Indiana Jones during his show:

Check out iplayer at approx. 34 mins.


He also uses the theme to the Professionals:

(and he uses the theme to Poirot)

I'll keep listening to the iplayer, see what else I hear.
