Expected to appear on Wednesday night Idol finale so far are:
Season 7 winner David Cook, Lionel Richie, Carlos Santana, Cyndi Lauper, Queen Latifah, the Black Eyed Peas and Keith Urban.
If I hear any more names, I will be sure to post them. While Carrie Underwood will be performing on Tuesday night, I wouldn't be a bit surprised to see her or other previous winners performing on Wednesday night as well. I'm sure there will be a lot of surprise appearances also, as FOX has been known to do in the past.
