Im pretty sure this isn't 100% correct but unless you compare it directly to
the original acoustic version you won't be able to tell (hopefully).
Read the story behind this song on wikipedia:

http://en.wikipedia.org/wiki/August_7,_4:15

Well anyway this is how I play it, I'm not that good at tabbing but here goes...

Verse 1, 2 and Intro

|--------0------------------------------------|
|----------0-----------3--------0-------------|
|------------0-------2--------0---0-----------|
|-----2------------0--------2-----------------|
|---2---------------------3-------------------|
|-0-------------------------------------------|

|--------0---------2-----0--------------------|
|----------0---------3-----3---3--------------|
|------------0---------2-----2---2------------|
|-----2------------0--------------------------|
|---2-----------------------------------------|
|-0-------------------------------------------|

These 2 riffs alternate during the verses and intro
Also, there's a section in between verse 1 and 2 where there is no singing, however, the 
above riffs are still played.

Bridge

Not too sure on but you can play an Asus2 and improvise appregiating or just strum

Chorus (strummed)

Verse 3

Bridge (Asus2)

Chorus

Guitar solo

Not too sure on this either, Richie mostly improvises. You can strum Em D and
C through it though, as it is not a lengthy one.

Verse 4

Bridge

Chorus X2
