There weren't many actual MISTAKES to fix, 'twas a 
good tab, I just added a few things (a few?) because it 
was missing them... rock on :-P

alright (deep breath...). mysteriousdarkness's stuff:
Track 1 (Guitar 1): changed fingering on bars 26-33, 
50-57, 74-81, 90-97 
Track 2 (Guitar 2): changed fingering, namely on bars 
11-25 and the repeats of those bars (90-105; 123-141)
(I realise in the case of fingering I may not have helped 
the situation, but I hope I DID help, and not make it 
worse :-( )   
Track 3 (Lead vocals): previous vocals were only intro 
and outro, anything between bars 25 and 86 and 114 is 
new
Track 4 (Backing vocals): between bars 82 and 86 is 
new
Track 6 (Piano): nothing life-changing, just turned it up 
a bit :-D
New tracks:
Track 7 (bass) and Track 8 (drums)

Other stuff: 
	put in markers (red flags :-P)
	removed bars 42-43 and 66 (weren't 
supposed to be there)
	expanded 7x brackets at bar 82 to become 
82-89 and added backing vocals thereof

:-P, poor validators, enjoy! hehe....
 
Version 2.1

Guitar 1: changed back fingering on bars 26-33, 
50-57, 74-81, 90-97 

Guitar 2: Changed back the fingering on bars 11-24 
and the repeats of those bars (90-105; 123-141)

 I also corrected some of the marker information, using 
the information from Origin. (You can find the line-up 
information in the "Default Information" section), and I 
switched Amy's vocals back to synth voice.

other than the guitars (which you just made difficult) 
nice job on the other tracks mysteriousdarkness.
