This is a video of Rob Scallon (previously: playing on an electric guitar shovel, playing a piece of every Metallica song in order and performing metal on a harp) covering ‘We Wish You A Merry Christmas’ in reverse, with the video played in reverse. That was neat. Also a relief, because I 100% thought he was having a stroke at first.

Keep going for the video, and turn on the closed captioning for bonus fun.
