“The song became a Liberal radical anthem in the aftermath of David Lloyd George’s “people’s budget” of 1909 which proposed a tax in land. During the two general elections of the following year, ‘The Land Song’ became the governing Liberals’ campaign song.” (from https://en.wikipedia.org/wiki/The_Land_song)

Sound the blast for freedom, boys, and send it far and wide,
March along to victory, for God is on our side,
While the voice of nature thunders o’er the rising tide:
“God made the land for the people”.

The land, the land, ’twas God who made the land,
The land, the land. The ground on which we stand,
Why should we be beggars with the ballot in our hand?
God gave the land to the people.

Hark! The shout is swelling from the east and from the west!
Why should we beg work and let the landlords take the best?
Make them pay their taxes for the land, we’ll risk the rest!
The land was meant for the people.

The banner has been raised on high to face the battle din,
The army now is marching on, the struggle to begin,
We’ll never cease our efforts ’til the victory we win,
And the land is free for the people.

Clear the way for liberty, the land must all be free,
Britons will not falter in the fight tho’ stern it be.
‘Til the flag we love so well shall wave from sea to sea,
O’er the land that’s free for the people.
