LYRICS
As I went down in the valley to pray
Studying about that good old way
And who shall wear the robe and crown
Good Lord, show me the way
Come on, fathers
Let's go down
Come on down
Don't you wanna go down
Come on, fathers
Let's go down
Down in the valley to pray
As I went down in the valley to pray
Studying about that good old way
And who shall wear the starry crown
Good Lord, show me the way
Come on, mothers
Let's go down
Come on down
Don't you wanna go down
Come on, mothers
Let's go down
Down in the valley to pray
As I went down in the valley to pray
Studying about that good old way
And who shall wear the robe and crown
Good Lord, show me the way
Come on, brothers
Let's go down
Come on down
Don't you wanna go down
Come on, brothers
Let's go down
Down in the valley to pray
As I went down in the valley to pray
Studying about that good old way
And who shall wear the robe and crown
Good Lord, show me the way
Come on, sisters
Let's go down
Come on down
Don't you wanna go down
Come on, sisters
Let's go down
Down in the valley to pray
As I went in the valley to pray
Studying about that good old way
And who shall wear the starry crown
Good Lord, show me the way
Come on, sinners
Let's go down
Come on down
Don't you wanna go down
Come on, sinners
Let's go down
Down in the valley to pray
