Doctor who and the proclaimers

I know David Tennants era is gone by now but..this vid just recently came out to the public and who am I to not let ten fans get more of their doctor..In this case Tennant is a huge fan of the proclaimers apparently so to give him one last send off the whole cast and crew did a funny vid for the wrap up party using the most famous song the proclaimers ever did..you know the one I'm talking about..
