Hello this is cool, groovy song. I looked at other tabs and I didn't see them correct 
To my mind it goes like this: 
     Am                 Dm 
e|---------0--0--0----1--3--3--1--3--- 
B|------1-------3----3---------------- 
G|-----2------------2----------------- 
D|----2------------------------------- 
A|------------------------------------  This *** goes through all the song 
E|------------------------------------ 
 
Sometimes when I'm bored, I play the song just playing these two cords- Am & Dm in bigbeat for 2 steps each  
 
e|---------x-----------------x---------- 
B|---------x-----------------x---------- 
G|---------x-----------------x---------- bigbeat 
D|---x--x-----x--x--x--x--x-----x--x---- 
A|---x--x-----x--x--x--x--x-----x--x---- 
E|---x--x-----x--x--x--x--x-----x--x---- 
     d  d  d  u  d  u  d  u  d  d  u        count figure out for yourself coz i dont want to make mistakes. 
  This tab is for those, who doesn't know what bigbeat is. Try it first on muted strings, then add chords. BYE
