Thanks for catching that, Joan. The missing verse isn't in the Carawan Sing for Freedom book, but it is on the Len Chandler Folkways recording. Here is my transcription of that recording, which is different from the lyrics in the Carawan book in many places.

FATHER'S GRAVE
(Len Chandler)

With my swing blade in my hand, as I looked across the land
And thought of all the places that I’ve been,
Of that old house that I called home,
Where I’d always been alone
And of that weedy grave that held my dearest kin.

CHORUS: (after each verse)
And as I cut the weeds from o’er my father’s grave, father's grave,
I swore no child I bore would be a slave.

The old house was just a shell, there were weeds around the well,
And I touched that rusty hinge that held no door
Oh, the roof was caving in, It was always sort of thin,
And I found that place that the ash pan burned the floor.

I thought of all the glad and the good times that I had
With my pockets full of purple plums each fall
When the yard was wide and clean and the grass was short and green
Now the underbrush has laid its claim to all.

I learned of violence done by my mother's brother's son
Was it hate or hurt that held the hand to knife
Oh, it was trouble in the mind, yes that's the only kind
That could make my cousin try to take his father's life

It made me feel so bad, lost the best friend that I had
And I didn't get to hear the preacher pray
Yes, and I was only eight, no, I can’t recall the date
Nor the reason I was late, but a funeral just can’t wait
And when I got to church they were rolling him away.
