Wow. That was pretty cool. The Stones really earned my respect with that one. They could've just followed the timid rules of their network sponsors, self-censoring any objectionable lyrics, but they refused to do that.
When they scrapped their network-approved set-list and launched into "Sweet Neo Con" they proved they were bigger than the Superbowl and provided something far more memorable than just another timid, inoffensive, Up-With-People style halftime show.
