He sang 4 songs. He seemed to be having a problem with his earpiece but made a few jokes. After 4 songs said he was going to be back in 2mins. Next thing tannoy comes over to say couldn't sort out the technicality. Thought it was a joke. I appreciate he probably couldn't hear properly and wouldn't want to put his name to shit performance, but I would have expected Barry to come out and say it himself. There was a 75 yr old lady that said she had waited 60yrs just to see him in vegas. Never forget why you are still playing at 82. It's not your plastic surgery. Its your fans
