In the Simpsons episode 'Last Exit to Springfield' what is the original song that Lisa sings to? The lyrics are something like: So we march day and night, by the big cooling tower; they have the plant, but we have the power

It is the Union Strike Folk Song, written by Jeff Martin, Jay Kogen, and Wallace Wolodarsky, Simpson's staff writers.

Come gather 'round children,
It's high time ye learned,
'Bout a hero named Homer
And a devil named Burns.

We'll march till we drop,
The girls and the fellas,
We'll fight till the death
Or else fold like umbrellas.

So we'll march day and night,
By the big cooling tower,
They have the plant,
But we have the power.
