The Avett Brothers - Murder In The City (intro Riff) Chords & Tabs

Scott plays this on Austin City Limits with a capo on 4, but I think it may be different at other times.  Pretty sure this is the ACTUAL way to play the intro and give the melody an emphasis that just fingerpicking the chords doesn't do.
[ Tab from: https://www.guitartabs.cc/tabs/t/the_avett_brothers/murder_in_the_city_intro_riff_tab.html ]
e|-------0---0---0---0------0---0---0---0---0-----|
b|---1---1---1---1---1------1---1---1---1---1-----|
g|-----2---4---4---------0----0---2---2-------2-0-|
d|-----------------2---2------------------3-------|
a|-3----------------------------------------------|
E|------------------------------------------------|

I'm pretty sure the other tabs are mostly right for the rest of it, but this was really bugging me, so I thought I'd figure it out.

If you don't want to look, the progression is mostly:
C Em Am G F G C
Am G C

Have fun!
