Verse:
G6      Em7  Am7    D5
I could cry  salty tears --

Where have I been all these years?

Lit - tle  wow, tell me now,
     C        Am       D9   D5   G
How long has this been go - ing on?
 G6         Em7   Am7    D+5
There were chills up my spine,
G6         G7      CM7     Cm6
And some thrills I can't define;
G           Em7  CM7  Am7
List - en, sweet, I repeat,

Oh, I feel that I could melt;
CM7   Dm7   G7   CM7
Into heaven I'm hurled.
Em     Em7  Em7     Em6
I know how Columbus felt
 Am      Am7     D7
Finding another world.

G6       Em7   Am7       D+5
Kiss me once, then once more;
G6      G7     Cm7    Cm6
What a dunce I was before.
G        Em7       CM7     Am7
What a  break, for heaven's sake,

That makes thrice, let's make it four.
G    G  Em7        C        D7
What a  break, for heaven's sake,
