Man, this song is totally epic so I needed to tab it.
Thanks to the maiden board for the help and stuff.

All the basic parts are tabbed,
I'm not even going to insult you all with tabbing the solo,
'cause it'll probably be wrong, knowing me! Knocked up again in very little time.
Those who know the structure of the song will be fine.

Interlude (play the whole section twice)

Alternate pick this section, its quite difficult if you try all downstrokes.
Its quite tricky compared to the rest of the song.
Try it slow if you can't manage it yet, you'll get it eventually.

Harmony section

This bit was a total ass to work out. I'm assuming that its right as
I had my speaker system panned right and left to work it out.
Still feel free to offer your interpretations of it in the comments if you want.
I'm not 100% sure of this.
