Should the performer in question be identified by name? Some might say this would be an invasion of privacy, but then again, due to his line of work, isn't his identity fair game for the public to know?

It's like Mitt Romney and his taxes. If he wanted to remain a private citizen we have no right to see his taxes, but because he wants to be president and will set tax and economic policy, we have a right to know about his income and investments.
