Got this from watching her Letterman performance
capo 4th fret
the Am to C transitions are pretty quick and you just kind of hold the C 

intro: Em G x4
Em     G
She's 22
    Em           G
And she's loving you
      Em          G        Em           G         
And you'll never know how it makes me blue
         Am      C
Does it make you happy?

  Em        G
I'm holding on
    Em            G
To a thing that's wrong
    Em           G
'Cause we don't belong
    Em            G
But you like my songs
        Am      C
And you make me happy
        Am     C
Does she make you happy?

D       G     C
You can throw away
D       G    C
Every word I say

 Em           G
I'm standing still
 Em           G
On this hidden hill
  Em            G
And I'm looking around
  Em             G
For the right way down
      Am      C
To your distant valley

    Em       G         Em       G
Your flowers grow in the frozen snow
    Em         G            Em       G
And I'd like to know if it's all a show
        Am        C
'Cause you sure look happy
    Am        C
Are you really happy?

D        G        C
You'll just throw away
D        G     C
Every word I say
D      G       C
You can throw away
Em G x4
Ooo ooo...

    Am           C
Does she make you happy?
    Am           C
Does she make you happy?
    Am           C
Does she make you happy?
    Am           C
I'd like to see you happy 
 Am C x2
