I agree that the whole "concert for a cause" shlick is madly overrated, especially for something as ludicrously under-scienced as global warming. In response to the rapping over a song (and also Nick's post on covers) I would refer you all to the show Gov't Mule put on at Bonaroo (set list below), an excellent case of fantastically rocking covers (admittedly some of the original artists joined them for the covers of their songs - such as John Paul Jones!!!!!) and rapping (I think) over songs. It was one of the best concerts I've ever seen or heard. But nonetheless, I do agree that covers are typically a waste, especially in the case of store sold albums. And as for the rock criminals, I think we should turn them over to Mr. Lordi:
