A Poem On The Underground Wall

The last train is nearly due,
The underground is closing soon,
And in the dark deserted station,
Restless in anticipation,
A man waits in the shadows.

His restless eyes leap and scratch,
At all that they can touch or catch,
And hidden deep within his pocket,
Safe within it's silent socket,
He holds a colored crayon.

Now from the tunnel's stony womb,
The carriage rides to meet the groom,
And opens wide and welcome doors,
But he hesitates, then withdraws
Deeper in the shadows.

And the train is gone suddenly
On wheels clicking silently
Like a gently tapping litany,
And he holds his crayon rosary
Tighter in his hand.

Now from his pocket quick he flashes,
The crayon on the wall he slashes,
Deep upon the advertising,
A single worded poem comprised
Of four letters.

And his heart is laughing, screaming, pounding
The poem across the tracks rebounding
Shadowed by the exit light
His legs take their ascending flight
To seek the breast of darkness and be suckled by the night.

Raven's Child

Raven's child is chasing salvation, black beak turned white from the crack and the snow.
On the streets of despair the answer is simple, a spoonful of mercy can set free the soul.

The drug king sits on his arrogant throne, away and above and apart.
Even children are twisted to serve him and greed has corrupted what once was a heart.

Raven's child keeps vigil for freedom, trades for the arms that once made her strong.
With nuclear warheads and lasers in heaven, fear does the choosing between right and wrong.

The arms king sits on his arrogant throne, away and above and apart.
Bankers assure him that he needn't care and greed makes a stone of what once was a heart.

Raven's child is washing the water, all of her wing-feathers blackened with tar.
Prince William shoreline's an unwanted highway of asphalt and anger an elegant scar.

The oil king sits on his arrogant throne, away and above and apart.
Lawyers have warned him he mustn't speak and greed has made silent what once was a heart.

Yet there are walls that come tumbling down for people who yearn to be free.
Still there are hearts that long to be opened and eyes that are longing to see.

Raven's child is our constant companion, sticks like a shadow to all that is done.
Try as we may we just can't escape him, the source of our sorrow and shame, we are one.

The true King sits on a heavenly throne, never away nor above nor apart.
With wisdom and mercy and constant compassion, he lives in the love that lives in our hearts.

Raven's child is washing the water, raven's child keeps vigil for freedom.
Raven's child, chasing salvation, raven's child is our constant companion.

What's That I Hear Now

What's that i hear now ringing in my ear
I've heard that sound before
What's that i hear now ringing in my ear
I hear it more and more
It's the sound of freedom calling
Ringing up to the sky
It's the sound of the old ways falling
You can hear it if you try
You can hear it if you try

What's that i see now shining in my eyes
I've seen that light before
What's that i see now shining in my eyes
I see it more and more
It's the light of freedom shining
Shining up to the sky
It's the light of the old ways a dying
You can see it if you try

What's that i feel now beating in my heart
I've felt that beat before
What's that i feel now beating in my heart
I feel it more and more
It's the rumble of freedom calling
Climbing up to the sky
It's the rumble of the old ways a falling
You can feel it if you try
