Roustabout: from Gary's Bluegrass Site

Chorus: Well, it's a long long way
It's a long long way
To the Gulf of Mexico

Well, I make my home on the Mississippi
I'm a roustabout on a Steamboat line
Let's hit the deck on a Monday morning
Let's make the lock on a Saturday night

Well, I have me a gal way down in Vicksburg
And she used to stop every time I passed
Then she made off with a little rich man
With a new silk suit and a little mustache

This is a bluegrass roustabout song. Anyone know the origin?
