The Beeb can put the series on whenever they like. Unlike USian shows, there's nothing to say when it has to be shown. The first Jon Pertwee episode was in September. The Beeb regularly shift series around within the year - WDYTYA is a prime example. So the whole thing smacks to me of utter bolleaux.

But I don't actually give a sh!t any more. So they can do WTF they like.
