Pins and Needles: Doing The Reactionary Rag

It's darker than the dark bottom
It rumbles more than the Rumba
If you think that the two-steps got 'em
Just take a look at this number
It's got that certain swing
That makes you wanna sing
Don't go left, but be polite
Move to the right
Doing the reactionary
Close your eyes to where you're bound
And you'll be found
Doing the reactionary
All the best dictators do it
Millionaires keep steppin' to it
The Four Hundred love to sing it
Ford and Morgan swing it
Hands up high and shake your head
You'll soon see red
Doing the reactionary
Don't go left, but be polite
Move to the right
Doing the reactionary
Close your eyes to where you're bound
And you'll be found
Doing the reactionary
All the best dictators do it
Millionaires keep steppin' to it
The Four Hundred love to sing it
Ford and Morgan swing it
Hands up high and shake your head
You'll soon see red
Doing the reac-
Doing the reac-Tionary
So get in it, begin it
It's smart, oh, so very
To do the reactionary!

The song is from the play Pins and Needles. About the production:

The International Ladies Garment Workers Union used the Princess Theatre in New York City as a meeting hall. The union sponsored an inexpensive revue with LGWU workers as the cast and two pianos. Because of their factory jobs, participants could rehearse only at night and on weekends, and initial performances were presented only on Friday and Saturday nights. The original cast was made up of cutters, basters, and sewing machine operators.
Pins and Needles looked at current events from a pro-union standpoint. It was "lighthearted look at young workers in a changing society in the middle of America's most politically engaged city." Skits spoofed everything from Fascist European dictators to bigots in the DAR. Word-of-mouth was so enthusiastically positive that the cast abandoned their day jobs and the production expanded to a full performance schedule of eight shows per week. New songs and skits were introduced every few months to keep the show topical.
According to John Kenrick, Pins and Needles "is the only hit ever produced by a labor union, and the only time when a group of unknown non-professionals brought a successful musical to Broadway."
Originally written for a small theatrical production, the first production of "Pins and Needles" was directed by Samuel Roland. After a two week professional run, it was adapted for performances by members of the then-striking International Garment Workers' Union as an entertainment for its members. Because Roland was associated with left-wing causes, he was asked by ILGWU president David Dubinsky to withdraw. The better-known ILGWU production was directed by Charles Friedman and choreographed by Benjamin Zemach. It opened on November 27, 1937 at the Labor Stage Theatre and then transferred to the Windsor Theatre on January 1, 1939, finally closing on June 22, 1940 after 1108 performances. The cast included Harry Clark, who continued his acting career with roles in The Skin of Our Teeth, One Touch of Venus, Call Me Mister, Kiss Me, Kate, and Will Success Spoil Rock Hunter?.
The Roundabout Theatre Company produced a revival Off-Broadway at the Roundabout Stage 1 Theatre in 1978, which ran for 225 performances.
The Jewish Repertory Theatre presented a concert in 2003, to include songs and sketches from all versions of the show.
