(written by Bob Regan, Tom Shapiro)
I'm not quite sure what's goin' on
But all day through and all night long
I've been thinkin' about you
I've been thinkin' about you
The look in your eyes when you smile that way
The sound of your voice sayin' my name
I've been thinkin' about you
Just keep thinkin' about you
This single minded fascination I've got
Do you call it love
If you don't then what
All I know is I don't know what you've done
And this train ain't about to jump the track that it's on
In the back of my mind there's a secret place
But the whole world knows by the smile on my face
I've been thinkin' about you
Can't stop thinkin' about you
I know it's crazy callin' you this late
When the only thing I wanted to say is
I've been thinkin' about you
Just keep thinkin' about you
I Can't stop thinkin' about you
Always thinkin' about you
