The look in your eyes when you smile that way,

the sound of your voice sayin' my name.

This single minded fascination I've got, 
F#          B        F#           B 
do you call it love? If you don't then what? 
G#m                        C#7 
All I know is I don't know what you've done, 
         E                                        F#

I've been thinkin' about you, 
Oh, just keep thinkin' about you.
