The Oxford St christmas lights this year look like klieg lights. It makes me think that we’re expecting an air raid. And air raids are obviously a central part of the traditional British christmas. All it needs is a Zeppelin or a V2 flying overhead to complete the illusion.
Oh, and the gantries that the lights are mounted on are covered in posters advertising Harry Potter. Because christians love wizards. Or wizards love christmas. Or something like that.
