Watch. Squee. Repeat.

David Tennant is a big fan of The Proclaimers and they love him back and during the filming of his last episode of Doctor Who they preformed I'm Gonna Be (500 Miles) together with other actors, producers and all the crew. Everyone is in it (except, sadly, Sinead) but noone rocks as hard as Ood Sigma. It is so awesome. If by any chance you still haven't seen this here it is (if you did see it, you know what I just did to you):

I just can't believe it took them 2 years to release that.
