In _A Death in the Family_, James Agee's father sings him to sleep:

Ohh ev-ry time the sun goes down,
Dey's a dol-luh saved for Betsy Brown:
Sugah-Babe.

They's a good ole sayin, as you all know,
That you can't track a rabbit if there ain't no snow:
Sugah-Babe.

Oh it tain't agonna rain, an tain't agonn a snow,
But the sun's agoan ah shine, an the win's agoan a blow:
Sugah-Babe.

[Spelling is Agee's.]
