Okay, so I've been seeing a lot of different things for this song. I came up with 
this way to play it a while ago and its worked pretty well for me. It isn't 
perfect, but I think it sounds good. :)

Standard tuning. no capo needed.
For B I like to play the power chord. which is 

Also during breaks and the intro you just play through the verse progression. :)

E    A      E        A       E
Caroline my baby Caroline my sweet
E    A     E            B            E
If I marred Caroline so happy I would be
E          A       E                  A       E
I wouldn?t need no whiskey I wouldn?t need no wine
E          A            E           B            E
I wouldn?t need much of anything if Caroline was mine


E         A    E                   A      E
Her daddy is a preacher and may he rot in hell
E           A       E           B              E
I?d sell my soul to satan for a bucket from your  well
E               A        E                  A        E
Cuz I know that he don?t like me and I know he?ll disapprove
E                A     E                    B               E
But I?m going to marry caroline if it?s the last thing that I do


E         A     E                   A       E
Well if I was a painter I?d put you down in paint
E           A      E              B                E
I?d hang you by the mona lisa and put that girl to shame
E       A     E                     A     E
Or if I was a sailor and sailed the seven seas
E        A          E             B               E
I?d roll across the ocean just to bring you home with me.


E      A       E           A       E
Oh caroline my baby oh caroline my sweet
E         A       E         B              E
You make a man go crazy why won?t you come to me
E             A       E                   A      E
Cuz I?ve been feeling lonesome  and feelin kinda blue
E           A      E           B         E
I think I?d rather die than to be away from you



         A       E           A        E
She said boy you know you?ve caught my eye
         A        E           A      E
And I know you?re sweeter than apple pie
       A      E   A          E
But I like my men completely wild
E       E       B
So baby keep on tryin ? oh oh oh oh



E    A      E        A       E
