Billy Joel was angry at this live concert taping in the former Soviet Union due to the fact that the lighting crew kept shining on the audience. This made the kids stop dancing, because they were nervous the secret police would see their faces on video and harass them later. The Piano Man simply wanted them to have a good time at his show, and who can blame him?
The dude can certainly rage with the best of them, though. Reminds me of Trent Reznor at Lollapalooza ’91, minus the dorky braids and mid-afternoon strobe light.
