Antiquarians might add, from The Bosses Song Book:

There once was a union maid
Who always was afraid
Of socialists and anarchists
And the games that the C.P. fractions played.
She read the New York Post,
Thought Dubinsky was the most.
She fought the left
Till she was out of breath,
And this is what she'd say:

Oh you've got me scared, I'm sticking to the union
And Harry Truman,
As close as glue, man.
Oh you've got me scared, I'm sticking to the union,
I'm sticking to the union
Till the day I die.
