"Swing Down Sweet Chariot" (the title of the first song listed in this thread) is available at perhaps a surprising source (unless you know that the singer won three Grammy awards for his gospel recordings): Elvis Presley! He recorded it in 1960 for the "His Hand In Mine" collection, where it was simply credited as having been arranged by Elvis.
The lyrics used by Elvis closely match those printed above:

SWING DOWN SWEET CHARIOT

Chorus:
Why don't you swing down sweet chariot
Stop and let me ride
Swing down chariot
Stop and let me ride
Rock me lord, rock me lord
Calm and easy
Well I've got a home on the other side                     

Repeat chorus

Well, well, well, well, well, well
Ezekial went down in the middle of a field
Saw an angel working on a chariot wheel
Wasn't so particular 'bout the chariot wheel
Just wanted to see how a chariot feel

Repeat chorus

Well Ezekial went down and he got on board
Chariot went a bumpin' on down the road
Zeke wasn't so particular 'bout the bumpin' of the road
Just wanted to lay down his heavy load

Repeat chorus                  

Well I've got a father in the promised land
Ain't gonna stop until I shake his hand
Rock me lord, rock me lord
Calm and easy
I've got a home on the other side

Repeat chorus
