Ten Reasons Why This Video Wins.

1. Upright bass. Like an electric bass, but more intimidating.
2. Resonator mandolin. 'Nuff said. Also, it appears to have a peg at the fourth fret - what the heck? I think it's separate from his capo. *edit: electric banjo. That explains the peg.
3. Accordian, which is like a piano except more ridiculous because one side is a piano but the other side has 120 buttons, and then you have to work the bellows at the same time. Ben Lovett armed with an accordian = 1 pianist + 3 brass players. I want to learn how to play the accordian.
4. Acoustic guitar with untrimmed strings, which would be a tremendous health hazard to anyone standing to the left of Marcus Mumford, except everyone's eyes are closed 90% of the time so it's ok.
5. I have the same Kyser capo as the aforementioned Marcus Mumford.
6. Crazy-ass microphone.
7. Foot-stomping.
8. Everyone is really good-looking.
9. Brit-tish, anyone?
10. Oh yeah, and the song is amazing. Even live. Especially live.
