Now this is a perfect song for someone to parade with a Doctor Who theme.
I really an impressed with how well done this video is. The make the song fit the storyline of the show with minimal alteration, which is just brilliant.
So watch the video and enjoy and if you don't get it, then go and watch some Doctor Who. The basic set up of the video comes from the David Tennant years.
Even if you not into Doctor Who, it is still a fun video.
