Me?? I have met plenty, albeit mostly relatively minor celebs like local news readers past and present, one of which I actually worked with for a while, Forbes McFall, in his new job after leaving BBC Scotland, working as a teacher. I have also met people like Annette Crosby (with her dogs of the time, one of which was a 3 legged greyhound)... You know, the wife in 'One foot in the grave'?
Also the late Desmond Llwellwn (spelling?), or 'Q' as he was better known as from the Bond films.
Also various people at book signings like Will Self and..... Heck I can't ever remember now (the books must have been that memorable).
I have mosly seen Pete Waterman (I know I know) quite a bit at Railway events (he isn't just into.... Erm.... Music you know). I also seem to see the Royals quite a lot and have even said 'Hello' to the Queen (I know, I know, but I wasn't in the mood to say something rude), and I also see a lot of politicians (I once shook Tony Blair's hand - What WAS I thinking?!) and the odd footballer and other sportspeople too, mainly the Scottish (UK) Curling teams and the junior players as they practice on public ice sheets, not to mention seeing them play in competitions.
Oh, and we have a family friend who used to live opposite the late Ricky Fulton, and we used to live up the road from Rose Harvey, the Scottish Green Party leader, Patrick Harvey's mum.
There are others, but those are who I can remember right now.
.... Oh yes, and I once had an all too brief exchange on Twitter (in the days when I did it) with Boris Johnson about the Scottish referendum and building a new Hadrian's wall (his words)
