From his song “The Popular Wobbly”; vigilantes beat up IWW organizers for exercising their free-speech rights on February 9, 1912 in San Diego and this song first appeared in the 1920 edition of the Little Red Songbook published by the Industrial Workers of the World, also known as the Wobblies:
I'm as mild mannered as I can be,
And I've never done them harm that I can see.
Still on me they put a ban, and they throw me in the can,
They go wild, simply wild, over me.
