Don't know about Marian Anderson's, but is this what you're looking for?

EVERY TIME I FEEL THE SPIRIT

CHORUS:
Every time I feel the Spirit
Moving in my heart I will pray (2x)

Upon the mountain my God spoke
O'er the mount (OR from his mouth) came fire and smoke
All around me looked so fine
I asked my God if all was mine

Chorus

Jordan's River is chilly and cold
It chills the body but not the soul
There ain't but one train on this track
Runs to heaven and right back

Chorus


My hymnal gives it as "African American spiritual c. 1750-1875"
