 Springsteen goes back to the drum kit, where a tray full of water and a sponge are.In tours past, this was a classic moment of Springsteen the relentless showman; he would sponge off his head, gulp down water and spray it over the stage, revitalizing himself to keep on playing for a few more hours.Now, however, he took the sponge, pulled his pants out by his belt buckle, and squeezed the water down into his crotch.
