I just heard about this, because I saw my wife post about it, and I'm utterly blown away.
You know Chris Hadfield, right? He's the Canadian astronaut who back in 2013 lived aboard the International Space Station, and did a lot of tweeting from there. I followed him for a long while, as I'm sure many of you have. He's a marvelous human being.
He's also, as it turns out, a really great singer. He recorded a version of the famous David Bowie song, A Space Oddity, from the International Space Station and posted it as a YouTube video. It's brilliant.
See for yourself.
I'm grateful to live in a world with such a remarkable person in it.
