Well, so far, all the versions are more-or-less the same, with a few different words here and there.

THE DISHEARTENED RANGER

Come listen to a ranger, you kind-hearted stranger,
This song, though a sad one, you’re welcome to hear;
We’ve kept the Comanches away from your ranches,
And followed them far o’er the Texas frontier.

We’re weary of scouting, of traveling, and routing
The blood-thirsty villains o’er prairie and wood;
No rest for the sinner, no breakfast or dinner,
But he lies in a supperless bed in the mud.

No corn nor potatoes, no bread nor tomatoes,
But jerked beef as dry as the sole of your shoe;
All day without drinking, all night without winking,
I'll tell you, kind stranger, this never will do.

Those great alligators, the State legislators,
Are pu?fng and blowing two-thirds of their time,
But windy orations about rangers and rations
Never put in our pockets one-tenth of a dime.

They do not regard us, they will not reward us,
Though hungry and haggard with holes in our coats;
But the election is coming and they will be drumming
And praising our valor to purchase our votes.

For glory and payment, for vittles and raiment,
No longer we’ll ?ght on the Texas frontier.
So guard your own ranches, and mind the Comanches
Or surely they’ll scalp you in less than a year.

Though sore it may grieve you, the rangers must leave you
Exposed to the arrows and knife of the foe;
So herd your own cattle and ?ght your own battle.
For home to the States I’m determined to go,—

Where churches have steeples and laws are more equal,
Where houses have people and ladies are kind;
Where work is regarded and worth is rewarded;
Where pumpkins are plenty and pockets are lined.

Your wives and your daughters we have guarded from slaughter,
Through con?icts and struggles I shudder to tell;
No more we‘ll defend them, to God We’1l commend them.
To the frontier of Texas we bid a farewell.
