[Verse 1]
G                                         C            G
Bring the good old red book, boys, we’ll sing another song.
                                    A7               D7
Sing it to the wage slave, who has not yet joined the throng
G          C                 G        C        G
Of the revolution that will sweep the world along
D                       G
To One Big Industrial Union.

[Chorus]
                      C                 G
Hooray! Hooray! The truth will make you free.
                     D
Hooray! Hooray! When will you workers see?
G                    C           G     B7    G
The only way you’ll gain your economic liberty
D            D7         G
Is One Big Industrial Union.

[Verse 2]
G                                  C                G
How the masters holler when they hear the dreadful sound
                              A7               D7
Of sabotage and direct action spread the world around;
G                      C                G     C          G
They’re getting ready to vamoose, with ears close to the ground,
D                         G
From One Big Industrial Union.

[Chorus]
                      C                 G
Hooray! Hooray! The truth will make you free.

Hooray! Hooray! When will you workers see?
G                    C           G     B7    G
The only way you’ll gain your economic liberty
D            D7         G
Is One Big Industrial Union.

[Verse 3]
G                                         C            G
Now the Harvest String Trust, they would move to Germany;
                                  A7           D7
The Silk Bosses of Paterson, they also want to flee
G                      C                  G       C     G
From strikes and labor troubles, but they cannot get away
D                         G
From One Big Industrial Union.

[Chorus]
                      C                 G
Hooray! Hooray! The truth will make you free.
                     D
Hooray! Hooray! When will you workers see?
G                    C           G     B7    G
The only way you’ll gain your economic liberty
D            D7         G
Is One Big Industrial Union.

[Verse 4]
G                             C            G
You migratory workers of the common labor clan,
                                 A7               D7
We sing to you to join us as we foil the masters’ plan;
G              C                  G    C    G
You must emancipate yourself, you proletarian,
D                         G
With One Big Industrial Union.

[Chorus]
                      C                  G
Hooray! Hooray! Let’s set the wage slave free.
                     D
Hooray! Hooray! With every victory,
G                       C           G       B7      G
We’ll hum the workers’ anthem till all finally must be
D            D7         G
In One Big Industrial Union.
