I was at that show too. I know who you're talking about with the guy who looked like Axl. He had that same hat that Axl likes to wear (like the one at the beginning of the VMA's peformance). It was a great show. I was in the front row as well, but off to the side next to Pinchface's drums (by the way, that guy is insane). When I was waiting in line there was a guy right behind us dressed exactly like Buckethead, he fooled me at first, I thought it was the real guy (he even had a giant robot toy hanging out of his pocket), but I realized the hair was fake looking....plus why would Buckethead wait in line for his own show?
Buckethead did some pretty insane things like playing the guitar backwards and upside down simultaneously and later playing seemlessly while doing a karate kick to one of his plastic heads.
Classic moment of the night had to have been when he was handing out toys and came upon a banana and looked at it puzzled, then put it down on the amp and continued to hand out toys.
Great concert, I definitely recommend anybody take advantage if he's in your area.
