Very much a work in progress.
After listening to this a few more times, I've decided that I'm seriously overthinking this song. The chords below sound how it should if you were trying to play the guitar and bass parts at the same time, but this isn't how it was recorded! Find someone to play bass for you, and simplify.
Capo 7
Intro.. 022000
022000 He floats
x42020 around like a
x2443x paper plane
x02220
3x000x just stopping to
2x000x touch the ground
022000 before it rains..
x4432x before the
x2443x wind comes along
x0422x and
30422x (??) blows him away
On 2nd string - 0 2 4
320003 and sunny
x42220 days are spent by the
x5423x river just
x4222x dreaming of
300230 bridges to lead him
022000 away let the
Pre-Bridge
x44320 water continue its
xx543x lonely parade
xx5430
xx543x
xx5430
On 2nd string - 2 4 2 4 well now he's seen what
320033 - love can
54002x - do he
On 2nd string - 2 4 2 4 swears next time he'll see it
320033 - through
54002x - for the one who gets lost (?)
320033 - oooh
022000
244300
x2443x (ooh)
x0443x
30443x
022000
244300
