So fill up your glasses
And join in the song
The Law's right behind you
And it won't take long.
So come, you coyotes,
And howl at the moon
Till there's blood upon the sawdust
In "The Last Chance" Saloon.

On your way then you cowboys
The time will be soon
When there's blood on the sawdust
In "The Last Chance" Saloon.

It's your last chance of cussing
At a gunfighter's doom
It's your last chance of nothing -
At "The Last Chance" Saloon.

With rings on their fingers
And bells on their toes
The girls come to Tombstone
In their high-silk hose.
They'll dance on the tables
Or sing you a tune
For what's in your wallet
At "The Last Chance" Saloon.

On your way then you cowboys
The time will be soon
When there's blood on the sawdust
In "The Last Chance" Saloon.

It's your last chance of boozing
Where there's no-one to mind
It's your last chance of losing
And the first place you find.

It's your last chance for givin'
It's your last chance of rye.
It's "The Last Chance" for Livin'
And the last place to die.

There's gamblers from Denver
There's guns from the South
And many a cowboy
With a dry, dry mouth.
There's a rag-time piano
And a small back room
For to sleep off your troubles
In "The Last Chance" Saloon.

Four Days ride from the Station
And you're leaving at noon -
Then your one consolation
Is "The Last Chance" Saloon.
You've a good chance of swinging
It's your last chance to hide
And your last chance of singing
Till your last long ride.

It's your last chance of cussing
At your hard-earned doom
It's your last chance of nothing -
At "The Last Chance" Saloon.

So pick him up gentle
And carry him slow
He's gone kind of mental
under Earp's heavy blow.

It's your last chance of earning
Your gunfighter's fee
The pay is in dollars
But the bullets are free.

So it's curtains for Charlie
That barman of fame
He met Johnny Ringo
And he knew Johnny's name.

He knew Johnny's name
And he spoke it out loud
Now Charlie the barman
Has gotten a shroud.

Johnny Ringo has found her
Johnny Ringo's found Kate
The gunslinger's got her
Now what is her fate?

Johnny Ringo has seen her
She's coming his way
Johnny Ringo and Katie
Were lovers, they say.

It's curtains for Warren
They gunned the kid down
And them bad cruel outlaws
Are heading for town
So the Earps and the Clantons
Are aimin' to meet
At the OK Corral near
Calamity Street.

It's the OK Corral, boys
Of gun-fightin' fame
Where the Earps and the Clantons
They Played out their game.

They played out their game and
We nevermore shall
Hear a story the like of
The OK Corral.

So the cards they are drawn and
The chips they are down
Them outlaws and lawmen
Are headin' for town.

So them bad cruel outlaws
Are meeting up soon
And they've had their last drink in
"The Last Chance" Saloon.

So it's curtains for Ike and
For Billy and Phin.
Them bad cruel out laws
Has paid for their sin.

They paid for their sin and
They lost on the draw.
For the Earps they was faster
And they was the law.

So beware all you cowboys
Who's a-yearning' to sin
If the Earps is the lawmen
You ain't gonna win.

There also appears to be a sound file but it's not playing on my machine.
