I was excited to find this info. I am 59 and have sung this song as a lullaby first to my children and now my grandchildren. I learned it in choir in elementary school in Baton Rouge, Louisiana in about 4th or 5th grade (we sang it in two parts). These are the words as I remembered and resang them through the years:

Desert silver blue beneath the pale stars shine
Coyotes yapping lazy on the hill
Sleepy winks of light along the far sky line
Time for milling cattle to be still.....

So, now, the lightening is far away
The lonesome owl is calling
The night is softly falling.
So, now, there comes another day.
Oh, settle down, you cattle 'til the morning.

I have looked for the old school songbook with no luck...any ideas? Knowing the writers names may help. Thanks.
