Of course he should, he's sitting on a potential gold mine with FT and I wouldn't be surprised to see him come up with a spin off of some kind yet. And why not?
My idea would be 'Manuel's', a sitcom set in Manuel's tappas bar, with Polly as the Manageress. Now a rich and successful owner of a chain of Spanish eateries, Manuel feels sorry for a bankrupt, divorced and semi derelict Basil, and decides to give him a job running one of his restaurants, cue the madcap comedy we loved so much. Only thing against it is their age but wonders can be done with make up these days.
