David Bowie's death at the age of 69 has hit the entertainment world like a ton of bricks. His genius will be deeply missed, and one Facebook user has posted a tribute that has quickly gone viral because it's so touching. UK resident Gordon Wilson went to the Kelvingrove Museum in Glasgow, Scotland, writing, "Not a good day. Took myself off to The Art Galleries . . . this was moving." He posted a video of the organist there playing a cover of "Life on Mars," one of Bowie's greatest tracks. It's a gorgeous version, and it feels particularly heavy given the news. Check it out, and then listen to the original version.
