I decided to make my own chord tab for this song because all the others posted 
here are not correct. For starters they showed a Bsus2 chord instead of the Bm chord.
Just play the arpeggio (and strumming) parts with each one and see which one fits the
music you hear on the recording. Additionally, the chorus and refrain progressions
were not correct. So here it goes...

Verse 1 (play chord arpeggios)
            
I took a walk 

              
around the    

             
     world to 

        
ease my troubl

ed mind 
            
I left my body

              
 laying       

             
     somewhere

        
 in the sands 

of time 
            
I watched the 

              
world float to

             
 the dark side

        
 of the moon
