Standard tuning

Intro:
E5  D#m*  C#m7   D#m*

Verse 1:

    E5                         D#m*
The first time that I saw you, lookin' like you did
         C#m7                         Bsus4
We were young, we were restless, just two clueless kids
         C#m               B                     E5   D#m* C#m7  Bsus4
But if I knew then, what I know now, I'd fall in love

     E5              D#m*
On a bus in Chicago, three rows to the left
             C#m7                           Bsus4
You know my heart was racing for you, but we never even met
         C#m               B                     E5
But if I knew then, what I know now, I'd fall in love

Chorus:

       Asus2            Em7/G#
'Cause love only comes, once in a while
F#m11                   Bsus4
Knocks on your door and throws you a smile
    Asus2               Em7/G#
And takes every breath, leaves every scar
F#m11                    Bsus4
Speaks to your soul, and sings to your heart
         C#m               B                     E5   D#m*  C#m7  Bsus4
And if I knew then, what I know now, I'd fall in love

Verse 2:

      E5                    D#m*
On a sunny night in August, backseat of my car
           C#m7                         Bsus4
Instead of tryin' to get to know you, I took it way too far
         C#m               B                     E5
But if I knew then, what I know now, I'd fall in love, oh

Chorus:

       Asus2            Em7/G#
'Cause love only comes, once in a while
F#m11                   Bsus4
Knocks on your door and throws you a smile
    Asus2               Em7/G#
And takes every breath, leaves every scar
F#m11                    Bsus4
Speaks to your soul, and sings to your heart
         C#m               B                     E5
And if I knew then, what I know now, I'd fall in love

Bridge:

         Asus2                       Em7/G#
And oh I used up a lot of chances, I can't get them back
    G                              B
But if again it comes callin', I'm gonna make it last

Chorus:

       Asus2            Em7/G#
'Cause love only comes, once in a while
   F#m11                   Bsus4
It knocks on your door and throws you a smile
    Asus2               Em7/G#
And takes every breath, leaves every scar
F#m11                    Bsus4
Speaks to your soul, and sings to your heart
         C#m               B
And if I knew then, what I know now
           F#m11               B
Whoa, if I knew then, what I know now

Outro:
E5  D#m*  C#m7  Bsus4            E
                     I'd fall in love.
