there are only 2 max Lead Guitars playing at once. 
Sometimes it's both of them, sometimes they harmonize 
their own Lead parts. Instead, I have labeled which 
parts I know are played by whichever of the 2 on the 
parts. Whoever's listed was figured out by seeing them 
live and watching live videos, and also by consulting 
the guys themselves.
