There was apparently a poltergeist plaguing Joe last night. His guitar cut out on him during one of his solos in Walk Away and then again during Rocky Mountain Way. He didn't let the problems disrupt the song any more than necessary either time... he just continued on with the lyrics while the problem was being resolved... always the consummate pro
The first time appeared to be a problem involving his floor control board (you can see the tech frantically trying to fix the issue...)
The second time it was something to do with the wireless transmitter (you can see Glenn reaching over to help him so he can keep playing)
