CHORDS :



[Verse 1]
Am
Hey babe I got my eye on you
C                  G
Standing there on beacon avenue
Am
I'm walkin dead, Yeah I'll be shot down
C                          G
Love at first sight ain't messin around

Am
You take my hand, You lead me to dance
C                       G
A cinderella love story ends with a kiss
Am                      
Lights go out, and it's last call
        G             F              Em
Maybe next time I'll look before I fall

[Chorus]
                                      Am
And that's when you shot through my heart
C     G
Whoa whoa
       Em                        Am
Well you had me right from the start
C     G
Whoa whoa
   Em                   Am
A critical shot to the heart
C     G
Whoa whoa
     Em                       Am
Now my whole world's fallin apart
C     G
Whoa whoa
        Em                              Am
Cause you shot me straight through the heart

[Verse 2] 
Am
Your satisfaction, no guarantee
C                  G
All I know is I feel you in me
Am
I look around,This place is a mess
C                  G
I feel the air through the holes in my dress
 Am
Now it's so damn cold,Here in my soul
C                       G
And you'll never know how far I let you go
 Am
Downtown, love never lasts
      G                 F                  Em
And there's no way you can prepare for the past

[Chorus]
                                      Am
And that's when you shot through my heart
C     G
Whoa whoa
      Em                         Am
Well you had me right from the start
C     G
Whoa whoa
       Em                Am
A critical shot to the heart
C     G
Whoa whoa
         Em                  Am
Now my whole world's fallin apart
C     G
Whoa whoa
         Em                             Am
Cause you shot me straight through the heart

[Bridge]
Am
You broke my heart and threw it on the floor,
C                                G
Sayin I'm not gonna come back no more (x4)


[Chorus]
                                      Am
And that's when you shot through my heart
