GH:M - Intro + For Whom the Bell Tolls (Expert Vocals FC)

After succeeding with the Band Hero stuff last week, I decided to spend my week off tackling what can be seen as another hard game for vox players, in the form of Guitar Hero Metallica. The problem with me here is more based on learning the songs, as I am familiar with so little in comparison to previous games.
But still, I think I can be a quick learner if I got the first song "For Whom the Bell Tolls" in one take. This will be a prelude to what is there to come =)
Cheers!
