In the beginning it goes like this:

e------------------------------------------------------
b------------------------------------------------------
G------------------------------------------------------
D------------------------------------------------------
A----------------------8--8----10--6----8--10----------
E----8--8--8--10--6----------------------------6--8----




Later on in the song it's:

e------------------------------------------------------
b------------------------------------------------------
G------------------------------------------------------
D----------------------------------------------8--10---
A----------------------8--8----10--6----8--10----------
E----8--8--8--10--6------------------------------------
