[I made some changes to this to make it specific to the 1984/5 NUM Strike - for the changes I can remember making, I've put the original in red underneath]

Miner's life is like a sailor's
Board a ship to cross the waves
Every day his life's in danger
Still he ventures, being brave
Watch the rocks, they're falling daily
Careless miner's always fail
Keep your hand upon your wages
And your eye upon the scale

Union miners, stand together
Do not heed the Coal Board's tale
[do not heed the owner's tale]
Keep your hand upon your wages
And your eye upon the scale

You've been docked and docked again, boys
You've been loading three for one
What have you to show for working
Since your mining days began?
Worn-out shoes and worn-out miners
Blackened lungs and faces pale
Keep your hand upon your wages
And your eye upon the scale

In conclusion, bear in memory,
Keep this password in your mind
Workers' strength cannot be broken
[God provides for every miner]
When in Union we combine
Stand up tall, and stand together
Victory for you'll prevail
Keep your hand upon your wages
And your eye upon the scale
