In the MudcatThread Songs Written In English About The Spanish Civil War I have listed a song called No Pasaran by Gary Kaye, which you can hear using this link Gary Kaye NO PASARAN on YouTube

The lyrics of the Gary Kaye song refer to the Spanish Civil War but it is clear from the later verses that this song is of relatively recent composition. However, I have heard a recording of a song made in the 1970's which uses the same tune.
Does anyone know the original version of the song. The tune is also the tune used in this song on Youtube http://www.youtube.com/watch?v=cFa0LpT2OHU by a Russian group which ends their video by singing a version of the SCW song Los Quatros Generales I suspect it was originally a Russian song from the Soviet era.

No Pasaran by Gary Kaye

On Cable Street where comrades meet
They stopped the fascists in their tracks
As side by side they stood with pride
They turned the black shirt bastards back

Then down in Spain they felt the pain
Those heroes fought and there they fell
With Stalin's help a blow was dealt
They damned the fascists into hell

No pasaran No pasaran
We will not yield these streets today
No pasaran No pasaran
The people here will have their say

People said no, rivers won't flow
The blood will not spill in our land
So Powell's words stopped being heard
As decent people took a stand

Monsieur Le Pen he tried again
To be a fascist President
People of France they took their chance
And knocked him down with common sense

No pasaran No pasaran
We will not yield these streets today
No pasaran No pasaran
The people here will have their say

The BNP spread their disease
And dress it up as politics
We are not fooled we won't be ruled
By those who stand there spouting shit

This war's not won it's just begun
For every woman, child and man
So don't give in 'cos we can win
If we cry out no pasaran

No pasaran No pasaran
We will not yield these streets today
No pasaran No pasaran
The people here will have their say
