At least Gilby got to play on stage. That's more than Matt, who does rock a mean tambourine!!
On a serious note, I know Axl regrets not doing this, even if pride won't let him admit it. It's going to follow him around from here on out. At least the other guys were man enough to show up. Izzy gets a pass because he is buried under a stack of newspapers that fell over him in his mansion and can't call out for help. But at least he can use this time to write some songs while people figure out what happened to him.
