Lord of the Rings - The Magician - Bruce Dickinson 

This is a video about Gandalf kicking ass.
Lyrics fit the video quite well.
Song: The Magician ~ Bruce Dickinson
Lyrics:
I am the teacher, come to reach you
Take the old ways back to you
You were lost, but I found you
And it's your choice what to do
I've learned a few things as I've travelled through the years
Through the door of evermore...
I came through fire, came through water
Through the oily serpent's kiss
Climbed the mountain, chased the dragon
Thrown myself in the abyss
Do I make myself familiar to you now?
Cause I've been around you
And I'm glad I found you...
I am the living flame, and I teach the holy games
Teach the secret of the dance
Throw the future in the runes
Kick the sand in Satan's face
I'll put Jesus in his place
Shaman or priest, it's all the same
The magician is my name
(woah-oh-oh, oh-oh)
The magician is my name
(woah-oh-oh, oh-oh)
The magician is my name
(woah-oh-oh, oh-oh)
The magician is my name
(oh-oh)
And magic is my game
Now I know you, and you know me
We have secrets we can share
We can build a new tomorrow
From the trash of yesterday
It won't be the last time
And I'm glad I found you...
I am the living flame, and I teach the holy games
Teach the secret of the dance
Throw the future in the runes
Kick the sand in Satan's face
I'll put Jesus in his place
Shaman or priest, its all the same
The magician is my name
(woah-oh-oh, oh-oh)
The magician is my name
(woah-oh-oh, oh-oh)
The magician is my name
(woah-oh-oh, oh-oh)
The magician is my name
(woah-oh-oh, oh-oh)
The magician is my name
