Re: 7X04 The Power Of Three (Grading/Discussion) (SPOILERS!)
That's because it's the song that's played absolutely everywhere, all day long and all over Britain when it's Christmas. And I'm not joking. It's Slade. Of course, they don't actually play music in hospitals, but I guess they thought the audience might be too stupid to realise it's Christmas just with "December" on the screen and tinsel everywhere.
Try not to talk about me, it's only giving me what I want after all, and I do more than enough laughing already.
