Theme Song Lyrics

Outlaws, runnin' from the hang rope
Outlaws, runnin' from the gun
Outlaws, stayin' to the back trails
Hidin' from the sun

But there's no use hidin'
When the law starts ridin'
And there's no use runnin'
When the law starts gunnin' for the outlaws

You may be fast on the trigger
You may be lightining on the draw
Come sooner or later
You figure to tangle with the law

Your'e playing in a losing game
In the end, it'll always be the same

You'll be outlaws, runnin' from the hangrope
Outlaws, runnin' from the gun
Oultaws, stayin' to the back trails
Hidin' from the sun

But there's no use hidin'
When the law starts ridin'
And there's no use runnin'
When the law starts gunnin' for the outlaws
