I'm not quite sure what's goin' on, but all through and all night long, 
          B5             E5     C#5   F#5        B5         E5         G#5  F5 
I've been thinkin' about you,        I've been thinkin' about you. 
 
Verse 2: 
B5               
The look in your eyes when you smile that way,  
E5                       F#5 
the sound of your voice sayin' my name. 
          B5            E5      C#5  F5          B5          E5     G#5 F5 B5

Bridge: 
G#5                       C#5 
This single minded fascination I've got, 
F#5          B5        F#5           B5 
do you call it love? If you don't then what? 
G#5                        C#5 
All I know is I don't know what you've done, 
         E5                                        F#5 
and this train of thought ain't about to jump the track that it's on. 
 
Verse 3: 
B5                        
In the back of my mind, there's a secret place.  
E5                                F#5 
But the whole world knows by the smile on my face, 
               B5             E5     C#5 F#5          B5         E5 G#5  F5     
that I've been thinkin' about you.       Can't stop thinkin' about you. 
 
Verse 4: 

I know it's crazy, callin' you this late, 

When the only thing I wanted to say is that 

I've been thinkin' about you, 

Oh, just keep thinkin' about you. 


F#5             B5           E5     C#5  F5           B5         E5       G#5  F#5 
Oh, can't stop thinkin about you.       I'm always thinkin' about you...
