A couple of years ago I had occasion to pass through Mornington Crescent station in London and was touched to find that someone had thought to put a plaque up in memory of I'm Sorry a Haven't A Clue regular Willie Rushton , I guess if they haven't planned one already, one must be in the pipepline for Humphrey Lyttelton. 

I got a shock this morning when my wife told me that Geoffrey Perkins had died. I first heard of him in the credits for the Hitch-Hikers Guide to the Galaxy in about 1980, and if you've laughed at anything on British or Radio in the last 25 years, there's a good chance that it was touched by Perkins at some point; part of Mornington Crescent lore  is that he invented it. (An alternative version is that the panelists invented it to confuse a producer.)

Geoffrey Perkins listing on IMDB is immense, if there is anyone working in British comedy who hadn't worked with him, then have all worked with someone who has. That would make him one very few people of whom you could say "The world will be a less funny place without him."  I don't know the first thing about his private life, but if any of his friends or family happen to read this,  I hope there's some crumb of comfort to be found in the fact that a lot of people feel that they share your loss.
