DESCRIPTION:
The song may have become more well known since being included in the movie "Oh Brother where are thou", but it dates prior to 1867 when it was published in "Slave Songs of the U.S."
(from the best description on its history I could find at http://www.choralnet.org/view/257262 )

As I went down in the river to pray
Studying about that good old way
And who shall wear the starry crown
Good Lord, show me the way

O sisters let's go down,
Let's go down, come on down,
O sisters let's go down,
Down in the river to pray

As I went down in the river to pray
Studying about that good old way
And who shall wear the robe and crown
Good Lord, show me the way

O brothers let's go down,
Let's go down, come on down,
Come on brothers let's go down,
Down in the river to pray

As I went down in the river to pray
Studying about that good old way
And who shall wear the starry crown
Good Lord, show me the way

O sinners let's go down,
Let's go down, come on down,
O sinners let's go down,
Down in the river to pray

As I went down in the river to pray
Studying about that good old way
And who shall wear the robe and crown
Good Lord, show me the way
