If I could offer a wee suggestion?

Having known (and heard and sung) these songs since they were first written, I never understood them as presenting historical records of events. It was always my belief that their proper purpose was to build morale and help keep a sense of focus and solidarity in a struggle that was never going to be either quick or easy.

I remember a dear friend saying that irreverent protest songs of this type were potentially more useful -- especially on a march where pavement spectators might only catch a small section of one of the more wordy, hymn-like protests like 'The H-Bomb's Thunder': making melodic bullet points (snappy statements with much repetition) allowed bystanders to pick it up very quickly!
