SUCH an easy song to play! I didn't care for the last tab so I was just playing 
around on my guitar and I came across this, which also fits for the song.

D A G A 2x

Verse 1:
D             A       G     A
She rolls the window down
    D         A        G     A
And she talks over the sound
       D         A       G       A            D
Of the cars that pass us by, and I don't know why
    A             G        A
But she's changed my mind

Chorus:
         D                A
Would you look at her, she looks at me
              G                 A
She's got me thinking about her constantly
D             A          G     A
But she don't know how I feel
         D          A
Then she carries on without a doubt
  G             A
I wonder if she's figured out
    D     A        G    A
I'm crazy for this girl
    D     A        G
I'm crazy for this girl

Verse 2:
D           A      G       A
She was the one to hold me
    D         A        G    A
The night the sky fell down
    D          A        G
But what was I thinking when
    A            D
The world didn't end
          A            G
Why didn't I know what I know now?

Chorus:
         D                A
Would you look at her, she looks at me
              G                 A
She's got me thinking about her constantly
D             A          G     A
But she don't know how I feel
         D          A
Then she carries on without a doubt
  G             A
I wonder if she's figured out
    D     A        G    A
I'm crazy for this girl
    D     A        G
I'm crazy for this girl

Bridge:
      D            A            G             A
Right now, face to face, all my fears, pushed aside
      D                 A                    Em        G
Right now, I'm ready to spend the rest of my life, with you

Chorus:
         D                A
Would you look at her, she looks at me
              G                 A
She's got me thinking about her constantly
D             A          G     A
But she don't know how I feel
         D          A
Then she carries on without a doubt
  G             A
I wonder if she's figured out
