Axl has such a reputation for doing that or not showing up at all that I wonder why anyone spends money to go see him. people love to say these days that Jon isn't fair to fans , he doesn't care etc... but to me what Axl does is much more disrespectful and I've never known Jon to keep an audience waiting or decide at the last minute that he just can't go out there or to go out there play 3 or 4 songs get pissed at something and leave, all of which Axl has done.
