The Haunting song from the current iPlayer promotion on BBC

Have had the following song in our heads all day. Unfortunately Sony did not like the idea of embedding the official version, so I have gone for an alternative – Sony why be so stupid! Anyway, enjoy the track. I believe Rufus Wainwright or John Cale has done this version of the Leonard Cohen original in the movie. Not sure who sings the one used in the iPlayer ads.
