Would you have freedom from Wage slavery,
Then join in the grand Industrial band;
Would you from mis'ry and hunger be free,
Then come, do your share, like a man.
(Chorus)
There is pow'r there is pow'r in a band of workingmen,
When they stand hand in hand,
That's a pow'r, that's a pow'r That must rule in every land—
One Industrial Union Grand.
