I know there are a number of ways to play this song
 (and that the SWS version isn't the original). 
I may tab out the original acoustic version by Closer 2 Closure later.
Verse 1 & 2:
B       Bb                    G#
Is it naive to make plans that seem so far away?
Then:E|-------------------------------------------------------------------------|B|-------------------------------------------------------------------------|G|-------------------------------3-----------------------------------------|D|-------------1--4-----------1--------------------------------------------|A|-------2--4-----------2--4-----------------------------------------------|E|-------------------------------------------------------------------------|
                  "There's a reason I feel this way..."

Verse 3 uses the same chords as part 3 of the chorus (**). Feel free to leave 
comments and correct verse 3
