NEW ORLEANS - The last day of the New Orleans Jazz and Heritage Festival kicks off under grey skies again.

The festival's closing acts were rained out on Saturday after a deluge whipped through the area.

Organizers are honouring tickets on Sunday for those who were rained out Saturday.

Stevie Wonder, who was supposed to close the Acura Stage, gave an impromptu performance in a New Orleans nightclub instead.

One of the acts Sunday will be singer Lena Prima.

She has an interview on one of the festival's 12 stages and a performance 2 1/2 hours later on another, with the Lena Prima Band.
