The BBC's official Doctor Who website was today updated with the eleventh door on their annual Doctor Who Advent calendar. Inside today's door is a video of David Tennant and the well known Scottish band, The Proclaimers, singing along to "I'm Gonna Be (500 Miles)". The festive musical video can be seen at the online Doctor Who Advent calendar at the official Doctor Who website by clicking here. The twelfth door on the calendar will be made available to open from tomorrow, and some details regarding the door will be posted here, on The Gallifrey Vortex, when it is openable.
