I figured this out for standard tuning and I think it sounds alright

E--------------------------------------------------------------------------------------------------
B--------------------------------------------------------------------------------------------------
G-----------------------------------------------------------------------------------10-10-8-6-------
D------------------------------------11--11--9--8--------------------------------------------------
A-8--8--9--8--11--11--9--8--8--9--8----------------8--8--9--8--11--11--9--8--8--9--8---------------
E--------------------------------------------------------------------------------------------------

Then for the chorus I just go:        F                                       G
                               In the sun in the sun in the sun I feed as one Married married...etc.

Thats pretty much it thanx for reading my tab my names Ben thompson and I love beanbags.

Oh and for the chorus it sounds better if you use bar chords. Peace.
