I don´t know what happened in this case and I don´t even care. But overall I don´t like this type of private concerts. People paying are usually rich enough only cos they are criminals, dictators, etc. But let´s not act as if other artists don´t do it. Cos they do. Beyonce, Xtina Aguilera, JLo are the first ones who come to mind right now. Probably 90% of the artists.
