*A scheduled Black Eyed Peas benefit concert in Central Park was canceled yesterday due to severe thunderstorms – and thousands of fans who braved the rain and the oppressive heat were not pleased.

“What, Will.I.Am can’t play in the rain? Is Fergie’s hair gonna get wet,” Popeater quoted of Queens resident Brian Moriarty, 26, who lined up with his girlfriend at 3 p.m. hoping to get a prime general admission spot close to the stage.

The concert, which was expected to draw up to 60,000 spectators to the park’s Great Lawn, was originally scheduled for 7:30 p.m. Thursday, but was delayed an hour and then canceled all together because of the weather.

The concert to benefit the Robin Hood Foundation was also to feature appearances by Natasha Bedingfield, LL Cool J, Carole King, MC Hammer, and Debbie Harry.

“We won’t go,” chanted the crowd of some 20,000 New Yorkers who stayed on. And many of them did not. Police had shoo folks away. In a statement, the Robin Hood Foundation said: “The heat wasn’t going to stop them, the rain wasn’t going to stop them, but the lightning-it stopped them. It came down to safety for everyone.”

They hope to reschedule soon and will be providing more information “in the next week or so” on the foundation’s website.
