As a tribute, International Space Station Commander Chris Hadfield covers David Bowie's Space Oddity, while floating in space.  Just thinking about it gives me goose bumps.

Imagine David Bowie's pride swelling if he would have been able to see this touching tribute.  The sight of Commander Hadfield floating in space, singing about floating in space, is just chilling.  And, he's got a great voice, to boot!
