A lady friend of mine worked in the BBC light entertainment department and had some wonderful tales to tell of KW.

Once she was left alone in the office with him, while her boss went out to get a couple of other people. They heard their footsteps coming back along the corridor, and just before the door opened, KW dropped his trousers. As the door opened he was dicovered struggling to get them on again, he then turned to my friend and said "My God Cathy, you can really get your knickers back on fast". Mind you everyone would have known it was a joke as "Julian and Sandy" portrayed his true sexual inclination.

On another occasion she managed to get me a pass into the BBC canteen when she was taking him to lunch (it wasn't easy as a lot of people liked listening to him holding forth on different topics). I found him hilarious - I can remember a story about theatrical landladies.
Evidently to save money when they advertise in "The Stage" etc, they used to use abreviations - ie BSF meant Bathroom Same Floor. He would ask them if the lodgings were LTC - and invariably they'd say yes. When we enquired what LTC meant, he said "Landlady takes Cock".
