Seems that I'm goin' coo-coo,
Dizzy as I can be,
Since that day we met, I've been all upset,
Something's happened to me,
All I've got, I find,
Is a one-track mind!

At times I'm out of my head,
I act in the street,
Forgetful the whole day through,
I can't think of
Nothin' but love,
Concentratin' on you!

Although I have my own bed
I sleep in the street,
I can't figure two and two,
Oh, how I rave,
I'm nearin' my grave,
Concentratin' on you!

I had a perfect memory,
Until you came to town,
Now since your spell is over me,
Boy, I'm bughouse bound!

Don't matter what happened tonight,
Don't know where I'm at,
A-boop-oop-a-doop-a-doop-doop,
In course of time,
I lose my mind,
Concentratin' on you!

I put my shoe on my head,
My hat on my feet,
Forgetful the whole day through,
I can't think of
Nothin' but love,
Concentratin' on you!

I put my clothes on the bed,
Sleep on the seat,
Can't figure two and two,
Got crazy ways,
I'm in a daze,
Concentratin', baby, on you!

I had a perfect memory,
Until you came along,
Now since your spell is over me,
My brain seems all wrong!

Sometimes I stand in my flat,
Don't know where I'm at,
I pay bills before they're due,
Got you to thank,
My mind's a blank,
Concentratin' on you!
