Live, Brian ocasionally bars 15 and strum very fast.

Here are the chords he switches between in the verse and chorus.

|e|-0-0-0-0-|6|
|B|-3-3-3-3-|5|
|G|-2-2-2-0-|4|
|D|-0-2-0-2-|3|
|A|-0-0-3-2-|2|
|D|---------|1|

When brian plasy live, he plays this
the second time through the chords.

|e|-X-----|6|
|B|---X---|5|
|G|-----X-|4|
|D|-------|3|
|A|-------|2|
|D|-------|1|
Just use the notes from the chords you strum.
Do it about 3 to 4 times. 
On the live KEXP broadcast
, he just hit the 5th and 4th string once after the chords.

Outro: build up the outro in the same rhythm as before
Then strum fast.
*note: those are the 12th and 13th fret.
|e|-0--0--0--0-------|1|
|B|-13-13-13-13------|2|
|G|-12-12-12-0-------|3|
|D|-0--12-0--12------|4|
|A|-0--0--13-12------|5|
|D|------------------|6|
