Thats why darkies were born

Someone had to pick the cotton,
someone had to pick the corn,
someone had to slave and be able to sing,
that's why darkies were born;
Someone had to laugh at trouble,
though he was tired and worn,
had to be contented with any old thing,
that's why darkies were born;
Sing, sing, sing when you're weary and
sing when you're blue,
sing, sing, that's what you taught
all the white folks to do;
Someone had to fight the devil,
shout about gabriel's horn,
someone had to stoke the train
that would bring god's children to green pastures,
that's why darkies were born.
