If you kept a blue tarp, they're still useful at Jazz Fest.
Jon Cleary was able to finish his jazzy R&B set on the Acura Stage before rain started to fall. By the end of Dr. John's set it was a torrential downpour. Some people headed for the tents. Those who went to the Ponderosa Stomp showcase in the Blues Tent were rewarded with some great New Orleans R&B from Tami Lynn and later the frenetic James Brown-style act of Roy Hood. Others fought the rain and stuck it out for Billy Joel's greatest hits. Still others split the difference and finished the day in the Acura showroom tent. By the time Jazz Fest pulled the plug on all stages at 6:30 there were still plenty of people braving the elements at the Fair Grounds.
