IRISH WAYS & IRISH LAWS

Once upon a time there was,
Irish ways and Irish laws,
villages of Irish blood
waitin' for the morning,
waitin' for the mornin'

Then the Vikings came around,
turned us up and turned us down,
Started buildin' boats and towns,
they tried to change our living,
tried to change our living.

Cromwell and his soldiers came,
started centuries of shame
shot the farmers in their fields,
workin' for a living,
workin' for a living.

Again again the soldiers came,
burnt our houses stole our grain,
but they could not make us turn,
we are a river flowing,
we're a river flowing.

800 years we have been down,
the secret of the waters sound,
has kept the spirit of a man,
above the pain descending,
above the pain descending

Today the struggle carries on,
I wonder will I live so long,
to see the gates being opened up,
to a people and their freedom,
a people and their freedom
