Here's an early gospel version:

WHEN THE CHARIOT COMES
From: Old Plantation Hymns (1899)

O who will drive the chariot when she cu-hu-hu-hu-hums?
O who will drive the chariot when she comes?
O who will drive the chariot? O who will drive the chariot?
O who will drive the chariot when she comes?

King Jesus, he'll be driver, when she cu-hu-hu-hu-hums, etc.

She'll be loaded with bright angels, etc.

She will neither rock not totter, etc.

She will run so level and steady, etc.

She will take us to the portills, etc.
