Hi Ken,
I don't know if this is the one but...

Early In The Morning - Elmore James
(standard 12-bar)

Well, it's early in the morning
and my baby can't be found
Well, it's early in the morning
and my baby can't be found
I'm gonna pack up and leave her
if she don't stop running 'round.

Well, I've got to leave my baby,
'cause she gives me such a thrill
Well, I've got to leave my baby,
'cause she gives me such a thrill
Well , she takes me back in the morning
And I hope she will

She can get so sentimental
when the lights are way down low
She can get so sentimental
when the lights are way down low
The way that gal can thrill me
make any man come back for more
