I've always found it offensive when a singer decides to give the National Anthem their own stamp - It is a song of respect and veneration - not meant to be screached or jazzed up! Just my 2 cents.....
My husband and I didn't care for the 1/2 times show at all. Our 3 daughters thought it was great.
The Super Bowl seemed to be on a roll with having Rock icons play the 1/2 time show ----- what happened? There are so many they could have picked from!
