The comedy gods have smiled upon us. Stewart Lee's Comedy Vehicle is back again for a third series. Of course there is no god, comedy or otherwise, so let's just celebrate the return to television of contemporary stand up's smartest sage. In fact there are two smart sages for the price of one here. Chris Morris also returns to the screen in this series, replacing Armando Iannucci as the "hostile interrogator" who intermittently questions Lee in a darkened room during the programme.
