Simon and Garfunkel, I am a Rock

Heard a pretty queer Simon and Garfunkel song, "I am a Rock". Have a listen yourself http://www.youtube.com/watch?v=M7D5-WjC2M8&feature=related . The tune plays out like a cheerful Christmas carol but the lyrics are sad and brooding, they talk of jilted love. The lyrics go..

I am a Rock
A winters day
In a deep and dark december;
I am alone,
Gazing from my window to the streets below
On a freshly fallen silent shroud of snow.
I am a rock,
I am an island.

I've built walls,
A fortress deep and mighty,
That none may penetrate.
I have no need of friendship;
friendship causes pain.
Its laughter and its loving I disdain.
I am a rock,
I am an island.

Dont talk of love,
But Ive heard the words before;
Its sleeping in my memory.
I wont disturb the slumber of feelings that have died.
If I never loved I never would have cried.
I am a rock,
I am an island.
I have my books
And my poetry to protect me;
I am shielded in my armor,
Hiding in my room, safe within my womb.
I touch no one and no one touches me.
I am a rock,
I am an island.

And a rock feels no pain;
And an island never cries.

This is a band that I love for their consistency of sound. You know that you'll hear the strums of an acoustic guitar and clear lyrics when you play a Simon and Garfunkel song. Nice.
