Capo 2 (for original key)

D                 G
Once upon a time and long ago
Bm
I wore a pretty dress
         A                 D
And you put a flower in my hair
D
Said I shine like gold
G
From what you've never known
Bm
Said I am more precious
     A                        D
Than anything you'd ever been told


D                    G
So here's the story, here it goes
  Bm
A boy falls for a girl
            A                             D
Yeah, that story's just the same and same old
D                       G
She wants to fall so in love
         Bm                        A
But everyone around her tells her 'no'
A
But she don't care because


              D               G
'Cause we are one, when we're together
             Bm                 A
'Cause we belong, forever and ever
                   D                     G
'Cause when you're here, I've never been better
         Bm                          A
And when I'm in your arms, that's where I wanna be
                   D        G     Bm      A
So there's no stopping me, oohh, oohh


D                    G
She has to keep her distance
Bm                  A
But she don't wanna listen, no
D                    G            Bm
He tells her that patience is the key
         A
But this patience is killing me

D                    G
So here's the story, here it goes
Bm
I will be your princess
        A               D
You'll never have to be alone
                    G
You'll be my prince charming
            Bm
'Cause when I'm in your arms
   A
I know I'm home



              D               G
'Cause we are one, when we're together
             Bm                 A
'Cause we belong, forever and ever
                   D                     G
'Cause when you're here, I've never been better
         Bm                          A
And when I'm in your arms, that's where I wanna be
                   D        G     Bm      A
So there's no stopping me, oohh, oohh

D              G
You can't stop true love
Bm            A
So there's no stopping us
D              G
You can't stop true love
Bm            A
So there's no stopping us


              D               G
'Cause we are one, when we're together
             Bm                 A
'Cause we belong, forever and ever
                   D                     G
'Cause when you're here, I've never been better
         Bm                          A
And when I'm in your arms, that's where I wanna be
                   D        G     Bm      A
So there's no stopping me, oohh, oohh
