It's been a long time since I heard this but I'll try to help ya out. It's by the Canton Spirituals.
Come along my friend come along
Get aboard and ride this train
Nothing on this train to loose
Everything to gain.
The gospel train is coming
Coming around the bend
The Lord God said he's coming back
But one thing, he didn't say when
You've got to get your house in order
You see the lord he's coming again....I want you to know...
Nothin on this train to loose
Everything to gain.
Hope this helps,
Ruth
