I have worked in the backstage/production end of cable programs and performance venues many, many times. I've seen some strange behavior. I've witnessed some odd demands.
Since I am not able to blog about these experiences in detail, I will post a link to a lively page of examples taken out of real contracts for various performers and what they need to have backstage in order to work. I trust you will find it amusing.
Do not doubt they are for real.
