Yes - you'd be surprised how many do get their own sporting question wrong! In reality they actually get ages to answer so it's easier than it looks.
You seem to know a lot about it Mark - and you comment on cricket a lot. You're actually Phil Tufnell pretending to be a Watford fan aren't you?!
Well I do follow the cricket as a 2nd sport and have watched QOS for ages so maybe a bit of a anorak!
I remember when Emlyn Hughes and Bill Beaumont were captains and they were allowed to take part in the home or away round. Emlyn always went away, usually with hilarious results.
Before that weren't the captains Cliff Morgan and Henry Cooper? I seem to remember watching them on a black and white tv.
