Fans had been waiting for hours to see the band (and Taylor Swift who was also on the bill) after severe thunderstorms forced organisers to delay performances. At around 8pm, they were eventually told that the event had been cancelled and were asked to leave.
According to The New York Post, one police officer on duty told fans that "lightning caused the cancellation" of the charity concert in aid of the poverty-fighting Robin Hood Foundation.
Disgruntled attendees were understandable vocal about the situation: "I'd like to get my money back," said one woman who had stood in the rain, draped in carefully crafted a rubbish bag poncho. "We'd like Fergie to reimburse us for our garbage bags." Others took a more philosophical approach — one man reminded those around him that "life is full of disappointments".
"At least we're not getting hit by lightning," he added.
