'Follow the drinking gourd' lyrics
Refrain: Follow the drinking gourd, follow the drinking gourd, for the old man is awaiting for to carry you to freedom, follow the drinking gourd.
When the sun comes back and the first quail calls, follow the drinking gourd. The old man is awaiting for to carry you to freedom, follow the drinking gourd. [Refrain]
Now the river bank makes a mighty good road, the dead trees will show you the way. Left foot, peg foot, traveling on, follow the drinking gourd. [Refrain]
Now the river ends between two hills, follow the drinking gourd. There's another river on the other side, follow the drinking gourd. [Refrain]
