I don't think that this has been posted or discussed here yet (I remember posting in a thread about it but I think it was on another board). This is the song that astronaut Chris Hadfield co-wrote with Ed Robertson of the Barenaked Ladies. It is the first song recorded on Earth and in orbit and, beside members of BNL, features youth choir the Wexford Gleeks. In short - I love it. Bouncy, lively, and a beautiful reflection on the view of Earth from up there.
