Marshall Riley's Army

In October thirty-six they took a trip,
The men who made the ships,
Searching for some kind of salvation.
With heads held high, and dignified,
The towns folk and passers by,
Held them in some kind of admiration.
March on, Marshall Riley’s Army,
Marching for your rights,
You’ve surely earned them.
March on, Marshall Riley’s Army,
Marching for your rights,
The lessons you taught us,
Who has learned them.
Soldiers in the front line of the struggle,
For the right to work,
God gave me these hands just to be idle.
Why has holyness the bishop,
With his infinite christian wisdom,
Like Peter in when the cock crew had denied them.
And the yes men, and the press men,
In London Town all came down,
Brought with them the curious, and derranged.
And forty years has since gone past,
But you’re still down there,
If you’re working class.
Can anybody tell me what has changed?
