I love this performance by Diana Ross in the torrential rain that became a giant thunderstorm. I was in NYC that day and actually took a walk in Central Park for the only time. We had just arrived from Niagara Falls and the weather was very hot and sticky. A storm was coming; you could tell ... and it did!
Above is a photo from the Empire State Building on the next day, looking towards Central Park. The stage would still hsve been there for the second day's concert.
The view in the opposite direction has the Twin Towers and also the Statue of Liberty (far right).
