HAVE to be "entertained" CONSTANTLY because of lack of focus. Hence why we HAVE to have a full blown concert at the halftime of Super Bowls. As a FOOTBALL fan, I have never been at ANY game and thought.....I cold go for a concert right now!!! I have always been a U2 fan....especially the 1980s. During SB 36, I was in ZEEEEEERO mood for a U2 show. I just wanted to get on with the second half. Their concert did NOT help me feel better.
