Guy Sings Halo Theme in Empty Chruch

Full disclosure, I've never played Halo. I'm aware such a video game exists and is fun for people who enjoy such video games. I know there are a lot of people who enjoy such video games and Halo in particular that's why I'm sharing this. I'm told it's amazing. Sounds pretty cool I guess for a dude being awkward in a coke shirt in an empty church.
