[Verse]
C           G
You are the only one
           C
My one and only one
                     F
Together we've had a lot of fun
    G                   C
But what'll I do if you leave me?
[Chorus]
                       F
If someone else should come along
    G                   C
And take your love from me
                   F
Darlin', you could never know
    G              C
How lonely I would be
[Verse]
C           G
You are the only one
           C
My one and only one
                     F
Together we've had a lot of fun
    G                   C
But what'll I do if you leave me?
[Chorus]
                     F              
I've tried to be the kinda guy
G                     C
You'd wanna call your own
                       F
So please don't go and throw away
    G                  C
The truest love you've known
[Verse]
C           G
You are the only one
           C
My one and only one
                     F
Together we've had a lot of fun
    G                   C
But what'll I do if you leave me?
[Bridge]
F                   G              C
What'll I do if you ever take your love from me?
D                                     G
'Cause in your arms is where I always wanna to be
[Chorus]
   C               F
If you should ever go away 
   G                    C   
My eyes would fill with tears
C                  F
And the heartaches I would feel
      G               C
Would last a thousand years
[Verse]
C           G
You are the only one
           C
My one and only one
                     F
Together we've had a lot of fun
    G                   C
But what'll I do if you leave me?
[Outro]
G                   C
What'll I do if you leave me?
G                   C
What'll I do if you leave me?
G                   C
What'll I do if you leave me?
G                   C
