Thank you GUEST,Gerry ,
Below I have posted the link you gave to the " Young man From Alcala" in the form that Mudcat calls a "blue clicky" . Now the video can now be accessed directly by clicking on the following " blue clicky".

The tune sung in the Good Fight video did make me think of The Young Man From Alcala, but I did not remember the lyrics of that song well enough to make the proper connection . Yes The Good Fight song is clearly The Young Man From Alcala in a shortened form. Well done!
I have now, below, cut and pasted the comments made on The Young Man From Alcala   YouTube video about that song's lyrics

        
haralaboskesa
Against Franco's heel, Dutche's lackey

A Spaniard who hailed from Alcala
When angered would shout 'mucha mala!
' He'd toss a grenade at a Moorish Brigade And blew all the facists to Allah

haralaboskesa
Oh the Lincoln boys fought at Jarama
They made the fascisti cry 'Mama!'
They were holding the line for months at a time
And for football they would play with bomma
Yippy ..
.
A codger from ol' Albacete Took ...... ?
When asked how he felt he just hitched up his belt
And said I can't tell just as yetta
Yippy

Cracken1979

Oh the Lincoln Battalion by crackey
A bunch of brave bozos though whacky
They held down the line for months at a time
'Gainst Franco xxx and his lackey.
Yippy ....

't Was there on the plains of Brunete
Midst a hail of steel confetti
With our planes and our bombs we would xxx Franco's ranks
And pick out Italian spagetta

Cracken1979
...against Franco Il Duces's lackey

Below are the Lyrics which the site gives for the song,

THE YOUNG MAN FROM ALCALA

A Spaniard who hails from Alcala,
When angered would shout mucha mala,
I tossed a grenade at a Moorish Brigade.
And blew all those fascists to Allah,
Yippee ai attee ai ay.


O the Lincoln Battalion by cracky.
. A bunch of brave bozos though wacky,
They held down the line for months at a time.
'Gainst Franco, II Duce's lackey,
Yippee ai attee ai ay.

'Twas there on the plains of Brunete,
Midst a hail of steel and confetti,
With our planes and our bombs
We would smash Franco's ranks.
Got sick on Italian spaghetti,
Yippee ai attee ai ay.
.

O the Lincoln boys fought at Jarama,
They made the fascisti cry mama,
They were holding the line for months at a time,
And for sport they. would play wilh a bomba,
Yippee ai attee ai ay.


A codger from old Albacete,
Took on 16 goats for a betta,
When asked how he felt, he just hitched up his belt,
And said, I can't tell just as yetta,"
Yippee ai attee ai ay.

This seems to answer some of my puzzles-but I still think "tanks" is a more likely rhyme for "ranks" than "bombs" in verse three.

Thanks for all your help.
