It's not the original version. It's just how I like to play it. 
In the original version there are some more chords in the Chorus 
and some chords are just played in another way. 
If you want to play it this way but in the 
original key, use Capo on 4th fret. ;)
(KT Tunstall plays it in this key)

   022100    ** 577650
*  076450       x24400
 244200     x46650  
 466400
   x02220
*  x02200

INTRO:
    - - -    - -* -  -  -  -  -  -  - 

(the spaces between the chords indicate how long you play it. 
So the first E is played long and the F#m-G#m (the 2 chords) 
are played short. Listen to the song to understand it ;))
(if you want to play it the orignal way, play this intro twice, 
and play the chorus chords after that)
