WHICH SIDE ARE YOU ON? (updated)

Which side are you on, now?
Which side are you on?
Which side are you on?
Which side are you on?

The miners on the picket line
Have Eastover on the run
Until they sign with the union
They will not mine a ton.

The miners down at Brookside
Are a courageous bunch of men
And with their women by their sides
Each has the strength of ten.

Duke Power thought they'd win this strike
With the miners in misery
But the union will shove it down Duke's throat
With a miner's victory.

Which side are you on, now?
Which side are you on?
Which side are you on?
Which side are you on?
