Around five or six years ago I worked for an event arena here in the Houston area. Just so happens Ozz fest came that year and Ozzy was playing with Black Sabbath. I had to work behind the main stage in the heat guarding a Playstation tent that was set up in the back man it was miserable. Right before Sabbath came on they moved me to the grass hill where people sit to watch the concert. The sun had just set and suddenly lightening started to strike and the wind began to pick up out of no where. Right as the first lightning was striking the lights went off on the stage and Ozzy gets on a mic and does that signature laugh that he does. The curtain then drops and he goes into this song as the sky opens up and pours down hard on everyone. Of course this drives the crowd nuts. As a security officer there this pure terror because your not a cop at all and your not allowed to touch people unless they touch you. I looked at one of the police officers as people started losing it and disregarding all sorts of bullshit. She looked at me and said theres nothing you can do let them kill each other because everyone in the entire concert went crazy at the same time.
