Well the river bank makes a mighty good road

Dead trees will show you the way
Left foot, peg foot, travelin' on
Follow the drinkin' gourd

Follow the drinkin' gourd
Follow the drinkin' gourd
For the old man is waiting to carry you to freedom
Follow the drinkin' gourd

How did the use of the song Follow the Drinkin' Gourd help enslaved people in the Underground Railroad?
