Underground wall

So I just got home from another concert at KLCC.
The first part was great and powerful, loved it.
I totally disagreed with the piano piece though,
couldn't see what was so good about it. Sadly, since
I had been looking forward to it. The pianist was
great however, Simon Trpčeski, a genius it seems.

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 its silent socket,
He holds a colored crayon.

Now from the tunnels 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.

-More timeless music from Simon & Garfunkel.

I'm not much into cars, but I have to say the
Ferrari Enzo is the hottest one I've seen!

So what's this four letter poem? Well I know, but I
won't tell you. Music is about how we interpret it, yeah?
