I had the following conversation:
Noddy Holder : Show us your tits.
Me : F&%k off!
Noddy Holder : F&%k off then.
I sat next to Giles Brandreth at a dinner. That conversation was rather more stimulating.
My dog was in Doctor Who - the episode with the original 4 doctors in it. Sadly I wasn't with him at the time. In fact, that dog used to get about, his list of celeb encounters would be much longer and more impressive than mine.
I've been in a lift with Patrick Troughton (I didn't mention that he'd met my dog - it would've been embarrassing, the dog had clearly preferred Tom Baker.)
Other encounters include being in a train carriage with Jackie Charlton and with Jennifer Saunders (not at the same time), in a queue in Woollies behind Anton Rogers, saw Victoria Wood putting petrol in her car on the M1, used to buy my veg in the same shop as John Thaw and saw him now and again, also saw Sheila Hancock pushing her granddaughter (I think it was) in a pushchair.
I could list some others but you'd have to be in your late 50's or 60's and have been into folk music in the 70's. (Yes Annie, I remember Tommy Steele - I was thinking about Half a Sixpence recently, trying to come up with a name for Sixpence's first calf!)
Oh, and I was at Uni with Guy jenkin (comedy scriptwriter - co-wrote Drop the Dead Donkey with Andy Hamilton, amongst other things.)
