For now, Kay wants to concentrate on a novel he's been working on, though he told me he may indeed revive LunarBBDO, which was a great take on the UK ad business, well-written and funny ("cheeky" I believe, is how the Brits would put it.)
The UK ad scene is interesting to watch because it's still very old media-centric and also because ads-- and the people who make them-- are more well know over there. Ben and Scamp can still do posts on "famous creatives." Which isn't something we can do over on these shores.
I wish Ben much luck with his novel-- I will keep you posted as to publication date when he sells it-- and he will be missed.
