Confused? Prolly! Brain Melt! It was like 110 to 120 and NO SHADE while walking around on aluminum panels in an arena (the Cottonbowl) where there was no possibility of any wind circulating because of the seating. We survived that day by using squirt bottles of water and battery operated fans given out the day before by several vendors.
I never saw numbers posted of fans carried out on stretchers from heat stroke that day.
Ironically, a massive storm blew in before the scheduled end of the concert. They had huge fabric prints (35 or 40 feet tall and 15 or 20 feet wide) hiding the backstage area at the sides of the stage. The winds that night were ripping those fabric walls to shreads!
As we drove home the next day, I-35 and surrounding areas were flooded. Our windshield wipers quit working. Here we were flying up I-35 heading back to Kansas, hydroplaning (!!) with Verna leaning out the passenger window manually "working" the windshield wipers!
That's Texas for you! The weather gods down there must not like rock concerts!
Clapton Rocked! So did Jimmy Vaughan, John Mayer, Johnny Lang, Steve Vai, Joe Walsh, BB King, Robert Randolf, Buddy Guy, James Taylor, ZZ-Top, and more that I can't even remember off-hand. Unbelievable gig.
