BBC Newsreaders CIN performances therough the years

With CIN coming up this Friday, I was wondering if the fellow TV Forum-ers might have clips of the BBC newsreaders performances during Children In Need thru the years, back to Sissons and Buerk and beyond, up till (almost) now.

I know that some of those performances have been available on YouTube, but in some cases, they are either no longer available, the encoding quality made some clips almost unwatchable, or they are limited to certain viewers.

Any help would be appreciated.
