Blackstone Edge is the site of a famous Chartist gathering where Ernest Jones addressed 30,000 people on 2nd August 1846 – every year people still gather here to sing this song (and a few others!): https://www.youtube.com/watch?v=86orh7GOLcs – you can find more about this annual gathering here – http://blackstoneedgegathering.org.uk/?page_id=12

To the tune of ‘Battle of Hohenlinden’ –

O’er plains and cities far away,
All lorn and lost the morning lay,
When sunk the sun at break of day,
In smoke of mill and factory.

But waved the wind on Blackstone height
A standard of the broad sunlight,
And sung, that morn, with trumpet might,
A sounding song of Liberty.

And grew the glorious music higher,
When pouring with his heart on fire,
Old Yorkshire came, with Lancashire,
And all its noblest chivalry.

The men, who give,—not those, who take;
The hands, that bless,—yet hearts that break;
Those toilers for their foemen’s sake;
Our England’s true nobility!

So brave a host hath never met,
For truth shall be their bayonet,
Whose bloodless thrusts shall scatter yet
The force of false finality!

Though hunger stamped each forehead spare,
And eyes were dim with factory glare,
Loud swelled the nation’s battle prayer,
Of—death to class monopoly!

Then every eye grew keen and bright,
And every pulse was dancing light,
For every heart had felt its might
The might of labour’s chivalry.

And up to Heaven the descant ran,
With no cold roof ‘twixt God and man,
To dash back from its frowning span,
A church prayer’s listless blasphemy.

How distant cities quaked to hear,
When rolled from that high hill the cheer,
Of—Hope to slaves! to tyrants fear!
And God and man for liberty!
