I went in April of 2013 to a Joe Cocker concert in Frankfurt. Terrific experience...I was forty feet from the stage and you could see sweat dripping off the guy in buckets. He probably gulped down ten bottles of water before it ended (a good long concert).
Didn’t even know he was sick. Although certainly back in the day from the way he abused himself, it’s a wonder he made it to 70.
