When I was a little girl...mother sang this song to us and her mother sang it to her and her grandmother sang it to her mother. I would very much like to know where the song came from and possibly how old it really is.
Lyrics:

CHINK A BOO MAN

When I was just a little bitty fella
Just about so high
My momma use to tell me a story
bout a big bold bad man in the sky

One night when all the shadows were a creeping
and the howling wind went around so loudly blew
I sat down by her knee
and then she said to me
here's the story bout the Chink a Boo

Chorus: He's got great big shiny eyes
         He's got a great big mouth this size
         He walks like this and like that
         He eats up little children both lean and fat
         So run, run, run just as fast as you can
         And hide yourself away from the Chink a Boo Man

One night when I was walking cross the meadow
Just about a mile from home
It was then I heard a rustling in the bushes
Then I heard a low, low moan
I ran into my Mammy's house a flyin
I ran that mile in nothin honest true
And when I reached that door
To Mammy I did roar
MAW! I saw the Chink a Boo

Repeat Chorus

I have sung this to my children and my grandchildren and they as I did as a child, love it. I just finished singing it to my granddaughter on the phone who is a thousand miles away from me and she asks every time I talk to her to sing it.
