not sure if this info is out among most of the GN'R collectors but in 12/2011 "
Classic Rock" made a reissue of
Marc Canter's authorised book "
Reckless Road: Guns N' Roses And The Making Of Appetite For Destruction". this edition is bigger and put together little different. havent compared exactly yet but see some stuff here:
edit:
Marc Canter also praised the re-release himself that Classic Rock made a wonderful job (or similar, cant find the interview link right now).
