I have noticed that lately, at the end of an hour, they no longer seem to 'close' the show, but go straight over to the next presenter, waiting in the wings for the next hour's show, and don't even seem to say goodbye and thank you, and wrap up their own hour. It is really odd. And it's always about 4 minutes before the end of the show. It has seemed to take the guests by surprise too. A really abrupt ending. More time for some extra adverts, a long introduction to the next hour, and in a puff of smoke the previous hour is gone!
