This should be interesting. Thicke, as an opening act, is sure to take too much time. I have heard Jill say many times that she is not concerned about following any act, but she better be on her game thurs. Chaka has a crazy fan base here in NYC. I am hoping that they will get together for a few tunes, kinda what Jill did with Badu and Latifah, rather than duke it out.
