If true, it is very surprising. Surely in most venues the people responsible for back stage hospitality are not the same people responsible for lighting, electrics, sound installation and stage safety? Isn't it quite likely that one of those teams would have met the requirements perfectly, and the other would have cut corners? How about the situation where extremely professional and scrupulous venues do all the important things right but resent having to sort M&Ms for overpaid stars? Wouldn't it have made more sense for Van Halen to have their own electrical inspectors who would check safety and reliability of the installation? How do other touring rock groups make sure everything is set up correctly? How did Van Halen come up with this particular canary test among all others?
Is it really that conspiratorial that an extremely famous 20 year old acted like a dick, and that at age thirty he made up a story to cover up his youthful dickishness?
