UPDATE an alert reader found this message board post on the fracas, presumably from Paul Leary:

“The first thing I’d like to point out is that all these references to the “sound man” are actually references to the Webster Hall house stage monitor engineer, not our actual sound man. Our sound man Kevin has done an outstanding job. During sound check, there was a major problem with feedback in one (or both) of Gibby’s vocal microphones. Kevin had to come on stage after sound check and used an equalizer to correct the problem. After the show, he observed that his corrections had been bypassed for the show. If it feeds back on stage, there is no way to turn up vocals in the room. The monitor engineer did nothing to fix the feedback, his most important function for the job he was being paid to do.

This should have been a better show. Gibby was totally on top of his game. His wife was in the audience, and tons of friends. It must have been heartbreaking to have that guy s* on his performance and do nothing to fix it. Near the end of the set, during Gary Floyd, I looked over and see Gibby yelling at the guy, who responds by turning all stage monitors off completely. Gibby did not hit or bottle the guy. I heard the stage manager from across the hall thought that he had, and ordered him removed. We had another song or two to play before “Shah”, so we just went straight into that. Our set ends there anyway. I think the house lights didn’t come on, and the audience really stuck around for more. The kids SOR kids were evacuated. I went to the Beauty Bar and felt nothing but love.”

So, I guess my hunch about the staging was off mark. The bottle thing threw me off, as Gibby has been known to use movie prop bottles in fake fights before.
