I tabbed these chords out because none of the versions here on ug is right. 
If you listen properly, you can hear the F-G-A-G Bassline going through the
chorus. For playing the chords just for fun on the guitar you can ignore 
this bassline, of course.
Theres one chorus where only the piano plays (marked with *). Theres no 
bassline in it so the normal chords can be played. 
(For beginners: Dm/G = Dm & Em/G = Em)

Thats all - have fun! :)
