I saw both shows(8/12 and 8/13). I initially only had tickets to the first show but when we got to the Garden my friend had lost his tickets(way too stoned). This gave me an excuse to go the next night.
During the second show Chris was having problems with his connection. His Bass was dropping in and out. You could hear and see what was going on. He was yelling at his roadie to get it fixed. The guy brought him out a new cord and plugged him in. The problem persisted and Chris was pissed. What happened next was wild. When the roadie brought him another cord Chris punched him either in the shoulder or the face. Suffice it to say the roadie got the message and the problem fixed.
