Lowdermilk based his song on the gospel hymn,

Lyr. Add: PRESS ALONG TO GLORY LAND
by Emmett Sidney Dean, 1876-1951
(version by Rowe and Dean)

O ransomed souls, with joyous song,
Press along to Glory-land;
Extolling grace that saves the race,
Press along to glory-land.

Press along, glad soul, press along,
Giving out the message grand;
Letting love, God's love, be your song,
Press along to glory-land.

Anyone have this gospel hymn in their collection?
Don't know if these are Dean's original words. The song "The Big Corral" is based on this gospel hymn.
