Regarding the whole America's Got Talent audition. I assume that Russell wanted to hire a male vocalist to front his performance? The idea being it would showcase his songwriting abilities, rather than his ability as a performer?
If this is the case, it's hardly surprising that AGT wouldn't entertain him. Even if he were the most talented songwriter under the sun, the show is really focused on performance, not on songwriting. I suppose it's possible that if he were a part of a band and the band were outstanding performers, he could have got on that way, but applying as Russell Greer and then paying proxies to do the performance in his stead was never going to fly.
I suppose I need to dig up the material on his AGT lawsuit. I've never really paid much attention to that before. It never seemed of much interest. But Mr Hardin's latest filing has piqued my curiosity now.
