You can pluck around the three chords - Bm, G6 and A - to get more or like the same fingering progression as in the song.

Verse 1:
Bm                       G6               A    
I took a walk around the world to ease my troubled mind,
Bm                  G6               A  
I left my body lyin somewhere in the sands of time.
Bm                               G6               A  
I watched the world float to the dark side of the moon,
Bm                          G6  A   Bm
I feel there's nothin I can do,     yeah.

Verse 2 - same chords -:
I watched the world foat to the dark side of the moon. 
After all I knew it had to be somethin to do with you. 
I really don't mind what happens now and then, 
as long as you'll be my friend at the end.

Chorus - only downstrokes -:
Bm                      G6                A  
If I go crazy then will you still call me superman.

If I'm alive and well will you be there a holdin my hand,

I'll keep you by my side with my super human might, Kryptonite.

Verse 3:
You call me strong, you call me weak, but still your secrets I will keep, 
you took for granted all the times I never let you down. 
You stumble again and bump your head, if not for me then you'd be dead. 
I picked you up and put you back on solid ground.
