Now then Arch - as a de facto cast member (surely someone called Archer appearing from York would be far less far fetched than all of the horrors I've had to read) couldn't you sort them out?
Oh, it gets better. My Mum's maiden name is Grundy.... No, really!
My Dad, back in the 60s, worked as a travelling engineer for Avery the scales people. One day he stopped for lunch at a pub he used regularly, and the landlord addressed him as Mr Archer. The Landlord's elderly mother in law happened to be staying and heard this, and asked for his autograph... He obliged, but never knew which Archer she thought he was.
I remember when that shower scene went out, there was a piece on one of the current affairs comedy shows where someone said "and then Jolene said "oh, Sid!" and when Jolene says "Oh, Sid!" a man stays "Oh, Sidded!"
I once saw the Grundies (Joe, Eddie and Clarrie) at a Radio4 roadshow type thing, where they recorded a scene and got audience members up to do the sound effects, banging doors, pouring tea etc. I wish I'd been brave enough to volunteer, as that stuff fascinates me. (ditto foley artists in film)
