Personally, I think The Who is real in the sense that whoever created him is real. Kinda creepy but if you eliminate those who don't have a lot of time on their hands to post ad nauseum nor any sort of background in the industry, the list of potential alter egos is rather short.
Sorry, meant to say no background "working" in the industry. But now that I think about it, one would not necessarily have to have first-hand knowledge of the industry. Hell, one doesn't even need to be qualified to work with kids to get a job in this demented industry. One just has to have a certain mindset and a HUGE ego.
