This is one of the best songs by the Beach Boys and since no one tabbed it, I did it^^
Put capo on 1st fret and have some fun!!

G
Well I've gone steady with a lots of girls
     Bm
And to all of them I tried to be true
         C                         A
But I'm so glad I never promised them
                 D
What I promised you

             G
And that's I do (I do, yes I do)
     Bm
Take you (take you, I'll take you)
       C
For my wife (for my, for my wife)
A                     D
For the rest of my life (ah yes the rest of my life)

        G
Well I hear from my folks time and time again
        Bm
To make sure that I found the right one
           C                             A
And every time you meet your heart will beat
                    D
And you'll want to say

              G
You'll say I do (I do, yes I do)
      Bm
Take you (take you, I'll take you)
        C
For my wife (for my, for my wife)
A                     D
For the rest of my life (ah yes the rest of my life now)

repeat 4 times the chorus

 G      Bm       C       A       D
