I managed to get into contact with Neil Gore who wrote the play "Dare Devil Rides to Jarama" which features the John Kirkpatrick version of The Lancashire Lads, and he has very kindly sent me the correct lyrics for the song. I reproduce the full song lyrics below , which include verses not included in the YouTube video.

Hi Geoff,
Here's the lyrics in full for Lancashire Lads:


THE LANCASHIRE LADS
Traditional Song – new words written for Dare Devil by John Kirkpatrick

1. It was September '36
The Party men did say
There's a call for volunteers for Spain
We're bound to march away

CHORUS: For the Lancashire Lads are going abroad
                                  A victory for to gain
                                  To hoist the flag of freedom high
                           Across the coast of Spain

2. 'Twas on a Monday morning
The orders they came round
For gallant lads of Lancashire
To fight on Spanish ground

       3. To the Free Trade Hall in Manchester
             More came there every day
             They came because their open eyes
             Could see no other way

4. Sam Wild was there amongst them all
    Bert Maskey signed up too
    And Booths and Browns and Bensons came
    To join that swelling crew

5. There was Arnold Jeans and Maurice Levine
    Ralph Cantor and Rob Ward
    And lads from Oldham, Salford too
    All chose to come on board

[6. Walter Greenhalgh he was there
    All ready to take his turn
    And Smiths, Swindells, and Sprostons
    Who were never to return]
(This verse didn't make the final cut)

7. Nurses, doctors, they came too
    To help to ease the pain
    And tend the wounds of those who fell
    So they could fight again

8. So Southward down to Dover
    And across to France they'd sail
    To Paris and on to the Pyrenees
    They knew they could not fail

9. And on through Barcelona
    Albacete was their goal
    To join the British Battalion there
      And fight with heart and soul

Many thanks to Neil for this. His play "Dare Devil Rides to Jarama" has continuing performances in December and in the Spring of 2017 and is well worth a visit.LINk to Interview with Neil Gore about the play
