When I first heard pig iron I knew I had heard it before. Johnny Cash sung the version I probably heard but it is a song called "Rock Island Line". Pretty hard to do if you havent heard it but the song goes like a train with the lyrics picking up speed as the song goes.
ROCK ISLAND LINE
(Traditional / Huddy Ledbetter / Arr. Lonnie Donegan)
Lonnie Donegan & His Skiffle Group - 1956
Now, this heres the story about the Rock Island Line
The Rock Island line, she runs down into New Orleans
Theres a big toll gate down there
And, y know, if you got certain things on board
When you go through the toll gate
Well you dont have to pay the man all toll
Well, the train driver, he pulled up to the toll gate
The man only asked him what he had on board, and he said
I got livestock, I got livestock
I got cows, I got pigs, I got sheep, I got mules, I got- all livestock
Well, he said, youre alright, boy
You dont have to pay no toll
You just go right on through
So, he went on through the toll gate, and as he went through
He started picking up a little bit of speed
Picking up a little bit of steam
He got on through he turned a look back to the man, he said
Well, I fooled you, I fooled you
I got pig iron, I got pig iron
I got all pig iron
Down the Rock Island Line she's a mighty good road
The Rock Island Line, its the road to ride
The Rock Island Line, its a mighty good road
Well, if you want to ride you gotta ride like you find it
Get your ticket at the station of the Rock Island Line
It was cloudy in the west, looked like rain,
But round the curve come-a passenger train.
North-bound train on the south-bound track,
You were all right a-leavin but you wont be back
Well, the Rock Island Line she's a mighty good road
The Rock Island Line, its the road to ride
The Rock Island Line, its a mighty good road
Well, if you want to ride you gotta ride like you find it
Get your ticket at the station of the Rock Island Line
Now I may be right and I may be wrong
But youre gotta miss me when Im gone
Well, the engineer said before he died,
There were two more drinks hed like to have tried,
The doctor asked him what could they be
a hot cup of coffee and cold glass of tea
Well, the Rock Island Line she's a mighty good road
The Rock Island Line, its the road to ride
The Rock Island Line, its a mighty good road
Well, if you want to ride you gotta ride like you find it
Get your ticket at the station of the Rock Island Line
