Along with Go down Moses, this song is among the better known of the spirituals sung by slaves in the pre-Civil War American South to signal that an escape attempt was at hand. It's a nice song on its own, but I like it even better for the part it played in history. Like many songs, the words could be changed to pass messages. In the line "My Lord calls me, he calls me by the thunder," for example, change out the word 'thunder' for whatever the signal or meetingplace for the escape is to be. After a few rounds of "the lord calls me by thunder" and "the lord calls me by lightning" no one will notice if the lord then calls you at midnight behind the old woodshed (though messages likely weren't that obvious). Or you can make up whole new verses, that works too.

CHORUS: Steal away, steal away, steal away to Jesus!
Steal away, steal away home, I hain't got long to stay here.

My Lord calls me, he calls me by the thunder;
The trumpet sounds it in my soul,
I hain't got long to stay here.

CHORUS
Green trees are bending, poor sinners stand trembling;
The trumpet sounds it in my soul,
I hain't got long to stay here.

CHORUS

My Lord calls me, he calls me by the lightning;
The trumpet sounds it in my soul,
I hain't got long to stay here.
CHORUS

Tombstones are bursting, poor sinners stand trembling;
The trumpet sounds it in my soul.
I hain't got long to stay here.
