I think the other tabs posted are making the song
more difficult than it really is.  So, here's my 
2 cents.


Verse:

E--2--x-x-----------------3--x-x----------------
B--3--x-x-----------------0--x-x----------------
G--2--x-x-----------------0--x-x--------------0-
D--0--x-x----0-h4-0-h4-0--0--x-x----0-h5-0-h5---
A-----------4-------------2--------4------------
E-------------------------3---------------------
            

Chorus: 
   Bm    D     G     Bm    A
E--2-----2-----3-----2-----0--
B--3-----3-----0-----3-----2--
G--4-----2-----0-----4-----2--
D--4-----0-----0-----4-----2--
A--2-----------2-----2-----0--
E--2-----------3-----2--------
