As impressive as the staging and audio was on Roger Waters’ The Wall tour, the coolest thing was seeing a guy go from totally screwed up to totally at home is his own skin. His sincere gratitude in addressing the audience when I saw the show was inspiring. And this perforrmance with the guy he was at serious odds with for many years was beyond cool. Check this one-time-only performance of Rogrer and David doing Comfortably Numb in London.
