Tuning: down 1/2 step (Eb Ab Db Gb Bb Eb)| 
Capo:   none 
 
(Note that the guitar is tuned down a half-step.) 
There are two basic chord progressions in this song: 
 
progression 1: 
C# Bb Eb (that is: C# major -> B flat minor -> E flat minor) 
         (Yeah, I know the B flat minor looks weird as 'Bb'...oh well.) 
 
      C#     Bb     Eb               C#     Bb     Eb 
Eb |------|------|------|      Eb |------|------|------| 
Bb |------|------|------|      Bb |---3--|------|------| 
Gb |------|------|------|  OR  Gb |---2--|---4--|------| 
Db |--12--|---9--|---2--|      Db |---0--|---4--|---2--| 
Ab |--12--|---9--|---2--|      Ab |------|---2--|---2--| 
Eb |--10--|---7--|---0--|      Eb |------|------|---0--| 
 
 
progression 2: 
C# Bb Eb F G (that is: C# major -> B flat minor -> E flat minor -> F minor -> G major) 
 
      C#     Bb   Eb  F    G                C#     Bb   Eb  F    G
Eb |------|------|------|------|      Eb |------|------|------|------| 
Bb |------|------|------|------|      Bb |---3--|------|------|------| 
Gb |------|------|------|------|  OR  Gb |---2--|---4--|------|------| 
Db |--12--|---9--|-2--4-|--5---|      Db |---0--|---4--|-2--4-|--0---| 
Ab |--12--|---9--|-2--4-|--5---|      Ab |------|---2--|-2--4-|--2---| 
Eb |--10--|---7--|-0--2-|--3---|      Eb |------|------|-0--2-|--3---| 
 
The start of the song (the part with just guitar) has a slide up to the 
C# and plays progression 1.  The first verse is progression 1 then 
progression 2 (you can hear the Eb to f to G chords played right before 
the chorus).  The chorus is progression 2.  The rest of the song follows 
the same pattern: progression 1 in the verse, progression 2 at the end of 
the verse and in the chorus.  In the chorus, when he repeats "You and I 
wouldn't change a thing..." he repeats the end of progression 2: Eb -> F -> G. 
In the interlude/bridge (or whatever it might be called) after the second 
chorus, he plays C# -> Eb -> F -> G. 
 
 
As a side note: in my opinion, if you've only got one guitarist, it sounds 
better to play the full chords in the chorus...something like: 
 
      C#     Bb   Eb  F    G                C#     Bb   Eb  F    G
Eb |---2--|---2--|-0--2-|--3---|      Eb |---0--|---2--|-0--0-|--3---| 
Bb |---3--|---3--|-0--2-|--3---|      Bb |---3--|---3--|-0--0-|--3---| 
Gb |---2--|---4--|-0--2-|--0---|  OR  Gb |---2--|---4--|-0--2-|--0---| 
Db |---0--|---4--|-2--4-|--0---|      Db |---0--|---4--|-2--4-|--0---| 
Ab |------|---2--|-2--4-|--2---|      Ab |------|---2--|-2--4-|--2---| 
Eb |------|------|-0--2-|--3---|      Eb |------|------|-0--x-|--3---| 
 
The full chords give a more full sound to it. (-:

This is played during the bridge or whatever it is (starting at 2:12). 
For this melody only, the numbers are realtive to the twelveth 
fret (i.e. 1 means 13th fret, 2 means 14th fret, etc.): 
|-2-------2-5-6-3-| 
|-------5---------| 
|---2-3-----------|

Here's what the electric plays at the end of the song: 
This plays (starting at 3:53): 
("10" means tenth fret, not first fret then open, ditto for "11") 
|---------|---------|-------------|---------| 
|---------|---------|-------------|---------| 
|-----7---|-----9---|-------11----|-----9---| 
|-7-7---7-|-8-8---8-|-10-10----10-|-8-8---8-|

|---------|---------|-------------|---------|

|-7-7---7-|-8-8---8-|-10-10----10-|-8-8---8-| 
|---------|---------|-------------|---------| 
|---------|---------|-------------|---------| 
 
Then this plays (starting at 4:08):

Then there's this (starting at 4:22): 
("x" means mute the string, "s" means slide)

Listen for the timings in the last part, it's not too difficult.
