Astronaut performs David Bowie's "Space Oddity" in space

You don't see this every day... an astronaut performing  David Bowie's "Space Oddity" in space.  The song, performed by Canadian astronaut Chris Hadfield, is very well done and took several months to make.  Apparently, even Bowie liked it.  The music video was made with his permission.  Plus, Bowie even retweeted the video after it was posted online on Sunday.
