Alright, I saw that the tab that's highest rated wasn't exactly right but pretty close. 
watched the AOL Sessions video for the song and got the exact chords from what Dave plays.

Chords:
Am - xx2210
Am7 - 3x2210
F - 133211
G - 320033
Dm- xx0231
Bb5 - x133xx
E - 022100
D - 2x032x
Alright, now here's the song.

The intro starts out with Dave playing an Am and hammering on the C in the Am chord. It 
like this:

E---------------------|
B---0h1-1--1----------|
G---2---2--2----------|
D---2---2--2----------|
A-0------0-0----------|
E---------------------|

And then it goes:

Am Am7 F x 2

You should be able to hear when he switches between Am and Am because he hits the low G 
note when he switches between them.

The song goes like this:

Intro

then

Verse 2:

Same chord progression. then the chorus, and then the bridge.

Bridge:

Dm (xx0231@1)        F (133211@1)      C (x32010@1)G (320003@1)name="chord_x133xx@1">Bb5
Ring around the rosie,

Dm (xx0231@1)        F (133211@1)      C (x32010@1)G (320003@1)name="chord_x133xx@1">Bb5
Pocket full of posies,

Dm (xx0231@1)        F (133211@1)      C (x32010@1)G (320003@1)name="chord_x133xx@1">Bb5

Dm (xx0231@1)  F (133211@1)     C (x32010@1)   G (320003@1)       We all fall down,

then back to chorus, and then a verse, then another chorus. Then the outro, which is 
Dave going through the intro but the chord changes are a little faster and there's an E at 
end, so it's:

Am  Am7 F E

It goes:

Intro
