Where There's Life was a YTV show I think, and a spin off from Don't Ask Me, that featured Magnus Pyke ?
YTV was sort of ITV's de facto supplier of science/medical programming.
Yes, they had a science department at YTV who did a load of these pop science things, and Adam Hart-Davis produced most of them. Where There's Life wasn't really a spin-off of Don't Ask Me but it was the same sort of style with a studio audience who would frequently get involved in the features. I really would like a pop science show like that these days with lots of audience participation, I know ITV did It's Not Rocket Science but it wasn't quite the same.
Another YTV pop science show was Fun and Games, which was a similar vibe but about maths, presented by Johnny Ball. Actually the combination of Johnny Ball and the YTV science team seems a match made in heaven but apparently Johnny didn't enjoy it all and left after the first series...
Trivial Pursuit with Tony Slattery:
Defectors from Challenge (TV), IIRC hosted by Richard Orford and also the UK Play version of Ask the Family with Alan Titchmarsh.
Ask The Family was on UK Gold, of course, wouldn't quite fit on UK Play. And it was repeated on BBC2 as well.
There was another attempt to put Trivial Pursuit on the telly when BBC1 did a game show based on it in 1990, presented by Rory McGrath. I remember the prizes were all a bit odd, I remember the star prize in one was an "alien TV" which was a normal TV but with bits of plastic stuck to it, and the consolation prize was a bit of the set because it was made up of lots of weird bits of modern art. I think the whole series was a bit too stylised for mass consumption.
I remember it as the go-to programme for replacing certain Sky One programmes on CableTel output of Sky One due to certain programmes being satellite-only exclusive hangovers from the BSB/SkyTV days....
Indeed, in the early days of ONDigital there were various shows on Sky One and Sky Movies that couldn't be shown on ONDigital because they didn't have the rights to show them terrestrially, I remember Xena Warrior Princess was one of them. So they had an alternative schedule in the Radio Times for a couple of months, with Guilty! appearing quite frequently.
Three shows involving Tom o Connor for you. Firstly, on Tyne Tees, PickPockets, which was a snooker based gameshow. There is an episode on youtube.
Two others from the BBC. Firstly, a lunchtime show that ran for one series, The Tom o Connor Roadshow. The other, was a lunchtime game show, involving BBC news reports and local news teams, "That's news to me".
I was convinced for ages that The Tom O'Connor Roadshow was the first programme we ever recorded on VHS, but it was in 1987 and we got our first video in 1984 so it can't have been. I do remember coming home from school at lunchtime and seeing it though. As the name suggests, it came from a different place for a week at a time, and one day it snowed so much nobody turned up.
