It's not often I am mobbed by photographers, in fact, apart from being buttonholed once by an elderly lady in Benidorm who asked me if I was actor Bill Nighy (to my eternal shame I did sign an autograph), I have managed to avoid fame and, unfortunately, Mr Nighy's bank balance.

So it was gratifying last week to stand on the deck of the SPV Royal Clipper off the Isle of Capri and be surrounded by a squadron of small yachts and speedboats full of people all desperately trying to take photographs of me.

Well, probably not me, exactly.
