Vic and Bob presented A Nose Through Nature, from what I recall.
Indeed they did...
I remember the story at the time was that Bob got attacked by a skunk during it and the stink hung around him for weeks. I remember in the eighties getting scratch and sniff cards in the TV Times, although I think that might have been based around an advert rather than an actual programme.
I think that was just about it - I have a vague memory of some 3D elements on Live & Kicking (or Blue Peter) also. Children in Need itself had some 3D including the aforementioned Dr Who special and I remember a very striking Pet Shop Boys performance.
I've actually looked up that episode of Pops - from 2nd December 1993 - and as I recalled, the Pet Shop Boys weren't actually on it. They did do a Pops performance with a load of computer graphics but that was just a normal episode. On the episode itself Take That was the only performance in 3D, and there was also a "3D video" of U2 and the Top 40 Breakers were also in 3D, but from memory I can only assume they played the records over some stock 3D footage.
A few years before, back in 1991, there was another 3D thing on Going Live where the video for Seal's re-release of Killer was made in "3D", and the glasses came free with Number One magazine. But I remember they had traditional 3D glasses for some 3D content in the magazine, plus a sort-of 3D monocle for watching the video because it wasn't "true" 3D, it was all about depth perception and I think was just a dark glass.
I think this was back in 2007/2008 kinda time? I remember that Sainsburys were providing the glasses, and I persuaded my dad to pick four pairs up, and suggested that we had a 'family round the telly' evening watching the countdown show. When the 3D 'adult' genre was demonstrated as part of the show, I was rather embarrassed to have suggested we watched the thing!
Those 3D programmes on C4 rated very poorly, and I remember loads of people saying they couldn't find any glasses - because being free, people just took the whole box from Sainsburys and then flogged them on eBay.
