I read somewhere that the auto-tune was being used for the halftime show! MAN!! How bad would they have sounded w/o it??!! I am sure some sound person(s) lost thier job over this one. The Tron-like light show was cool. Pop singers should be banned from singing the National Anthem unless they sign a "Will Not Butcher" clause with the penalty being a multi-million dollar fine! My opinion, the National Anthem should always be done in concert Ab and by some type of band (at the Super Bowl).
