The Limeliters sang "The Battle of Gendesa" in both Spanish and English. If I remember them correctly, the English lyric for the first verse was

If you want to drop a line
You must know where you can find me
At the Battle of Gendesa
Where the fire tries to blind me

And I guess the song of the Lincoln Battalion is the one set to Red River Valley

There's a valley in Spain called Jarama
It's a place that we all know so well
For 'twas there that we gave of our manhood
Where so many of our brave comrades fell

We are proud of the Lincoln Battalion
And the fight for Madrid that we made
There we fought like true sons of the people
As a part of the Fifteenth Brigade

Now we're far from that valley of sorrow
Though its memory we'll never forget
In the midst of the struggles around us
Let's remember our glorious dead

I've seen a few other verses, but these are the most commonly sung.
