Not too sure about this episode, Catherine Tate was wonderful as usual and so was Tim McInnery (I wonder if Mr Halpen's first name is Percy) The story was so-so, just your average Evil-humans-enslaving-a-peaceful-race episode
As for the Doctor's Song ending maybe it refers to his Song of Sadness which could mean one of several things
