Chris Hadfield - Space Oddity

In what may be the coolest clip I've ever seen, Canadian astronaut Chris Hadfield bid farewell to his time on the International Space Station with the below version of David Bowie's classic, Space Oddity.  Best comment on YouTube: "Most expensive music video ever."  CNET has more:

Mixed with the help of staff at the Canadian Space Agency, musician Emm Gryner, and others, the cover features a somber piano intro and modified lyrics that reference the Soyuz capsule that will return Hadfield to Kazakhstan. When the mustachioed commander sings "I'm floating in a most peculiar way" while actually floating up in space, Hadfield wins the Internet, as one commenter suggests.

From David Bowie's Facebook page: "It’s possibly the most poignant version of the song ever created."  Incidentally, Hallo Spaceboy was Bowie's 1996 single, the hit remix of which featured the Pet Shop Boys.
