It was a secretive affair -- scheduled as "a special show with will.i.am and friends". When we received our Chairman's wristbands for the floor in our registration packet the lady wouldn't even tell us what they were for. Just for "tonight". And that we "wouldn't want to miss it for anything" (I'm pretty sure the second half pertained to the announcing of the Chairman's winner at the concert/filming).
edit: I will say that each Finale I've been too didn't seem worth it, but I'm a bit of a party pooper, especially when I'm tired...
