"Follow the Drinking Gourd" is an American folk song first published in 1928. The Drinking Gourd is another name for the Big Dipper asterism. Folklore has it that fugitive slaves in the United States used it as a point of reference so they would not get lost.  According to legend, the song was used by a conductor of the Underground Railroad, called Peg Leg Joe, to guide some fugitive slaves.

In 1955, singer Randy Sparks heard the song from an elderly street singer named John Woodum. These lyrics diverged greatly from the Parks and Hays versions and included no geographical information. Sparks later founded The New Christy Minstrels, with whom he recorded a version of the song based on Woodum"s lyrics.
