Found it!!!!

Song of Liberty,

Lyrics by Brian Warfield Music by Verdi (The Slaves Chorus from Nabucco)

Stand beside me for peace and for liberty
For freedoms denied to many nations.
With sad emotions ,for borders that run through these lands
In the hope that with justice and peace all will be free.

Free the earth of weapons of war, of death and destruction,
Should the strong deny the weak when it's justice we seek for all.
With sad emotion for people of these troubled lands
And the hope that all nations at war will find peace

For united we stand,
Linking our hands throughout this world
Making chains of love that won't be broken.
We are singing this song,
Knowing our heart cannot be wrong
With the love of all struggling people
For I hate to see children crying

We must stop all their sorrow and dying.
Stand beside me for peace and for liberty
With the hope that all nations at war will find peace
It's a wish that our lands will find justice with peace
We will sing you this song , just for you liberty , liberty , liberty.

The Aria is Va Pensiero - absolutely nothing like La Co Cera!!!! Apologies
