Ca Ira: Opera in Three Acts: "To Laugh Is to Know How to Live..." - Roger Waters

To laugh is to know how to live

To see is to know everything

To read is to hold the key that you need

The key you need to set you free

All the world can see that in this great library

There’s a good medicine against tyranny

And the movement of the heavens

Though it may last forever

sees no right, no wrong, no weak, no strong

And the star you see in the sky and the moon and the sun

Shine on prince and pauper alike and favour no one

The politics of the Rights of Man

Is the sharing of apples with an even hand

TO plant a tree were birds my sit

But who in France will nurture it
