In The Shadow Of Steel

I have just found out 
I'm the chosen one 
I am the great Sir Knight 
Rescue young maidens 
Fighting evil dragons 
I'll defeat all the giants 
In the shadow of steel 
I am Don Quijote 
Of La Mancha 
Evil forces stand back! 
And you black knights 
Out of darkness 
You'll beware of my attack 
In the shadow of steel 
They say I've gone mad 
And my fate's rather sad 
All the fame and the glory 
I seek but they say I've read too many stories 
In the shadow of steal
