The feud was mentioned on "The Wright Stuff" this morning, and they went into a bit of detail (I wasn't even aware of it until yesterday).
Apropos to absolutely nothing, when I lived in London, I used to work with a guy who'd worked for the Beeb some years before, and had had Dick Clement or Ian la Frenais as his best man for one of his weddings. He said, as a best man he was absolutely useless ..... but when it came to the best man speech, it was the best ever.
