Some explanations:
1.For the intro and RIFF 7 you must fret the low E string on the 1st
fret, prebend a whole step and then release (that's what the R means).
2.Blank columns (as in Riff 1) do not count in timing. They are used 
only to distinguish the tab numbers.
3.p=pull-off h=hammer on



Song flow and lyrics:

[Intro] X3
[Riff 1] X2
w/Riff 2
Has he lost his mind? Can he see or is he blind?
Can he walk at all? Or if he moves will he fall?
[Riff 1]
w/Riff 2
Is he 'live or dead? Has he thoughts within his head?
We'll just pass him there. Why should we even care?
[Riff 3]
[Riff 1] X2
w/Riff 2
He was turned to steel in a great magnetic field
Where he traveled time for the future of mankind
w/Riff 4
Nobody wants him. He just stares at the world
[Riff 5]
w/Riff 4
Planning his 
vengeance that he will soon unfold
[Riff 5]
[Riff 1] X2
w/Riff 2
Now the time is here for Iron Man to spread fear
Vengeance from the grave kills all the people he once saved
w/Riff 4
Nobody wants him. They just turn their heads
[Riff 5]
w/Riff 4
Nobody hepls him. Now he has his revenge
[Riff 5]
