I was at this concert and Glenn was awesome, as always, and the highlight of the show for me. One weird thing that happened, and only when one of Ray's song was about to be played, all the power went out and the lights went down...then after a few minutes, and some joking around on the mic, the power came back on. As soon as they started playing Ray's tune again, bam the power went out again, it was cool and very trippy. I forget who said it on the mic but someone said "okay Ray, we hear you"

It was a cool experience!
I'd love to see a copy of the show too, here's the ticket stub I just found while doing some spring cleaning in the garage:
