This is really easy. Forget the G string.
It pretty much does this the entire song except one part.
G----------------------------------
D----------------------------------
A----------------------------------
E-2-2-2-2-2-2-2-2-2-3-3-3-3-3-3-3-3
Then when the whole band plays it goes
G----------------------------------
D----------------2-2-2-2-----------
A-----------------------3-3-3-3----
E-3-3-3-3-3-3-3-3------------------ this repeats
Then just listen for the timing and there you go.
