It doesn't matter what the fans think. It doesn't matter what the HOF thinks. It doesn't even matter what Ilan thinks. In the grand scheme of things, all that matters is what Trent thinks since he (and ONLY he) is the one being inducted. And if Trent thinks Ilan should be performing with NIN that night to celebrate his big night......Then Ilan should be performing with NIN that night. The end....And if Trent is cool with Ilan not being there, then he doesn't need to be there.
