To my mind, the best recording with this title is the doo-wop classic, recorded by the Cleftones (1956) and later by Dion:

LITTLE GIRL OF MINE
(Herbert Cox & Morris Levy)

Oh, little girl of mine, Gee, you sure look fine;
Yes, you appeal to me, I'll never set you free.
Be my lovin' baby till the end of time,
I can't seem to get you off my mind, my baby.
The boys will roll their eyes as we go strollin' by.
It's not so hard to see, that they all envy me
'Cause you're my lovin' baby, you belong to me.
That's the way it was meant to be.

Oh, well, now I know I love you so,
I'll never, I'll never let you go,
I need your love, oh, so much;
I thrill to your touch.

Oh, well, now I know I love you so,
I'll never, I'll never let you go,
I need your love, oh, so much;
I thrill to your touch.

So little girl, stay true; that's all I ask of you.
Be mine and mine alone, don't leave your happy home.
'Cause I love you, baby, and I always will,
You're my one and only thrill, my baby
My honey, my sweet thing.


The "mouth music" that accompanies the song is "Lil lil lil lil lil" or something like that, five times, over and over again.

There's a completely different song with the same title, recorded by Faron Young. Can't say I like it...
