(Tom Shapiro/Bob Regan)

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 of thought 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,
that I've been thinkin' about you.
Can't stop thinkin' about you.

This single minded fascination I've got,
do you call it love? Well if you don't then what?
All I know is I don't know what you've done,
and this train of thought ain't about to jump the track that it's on.

I know it's crazy, callin' you this late,
When the only thing I wanted to say is
I've been thinkin' about you,
Oh, just keep thinkin' about you.

Oh, can't stop thinkin about you.
I'm always thinkin' about you...
And I do love thinking about you.....
