Like I said on one of the other seven billion threads about pre-match: When you have 7000 people in a ground, all of whom have wildly diverse tastes (apart from following the same rugby team), it's going to be nigh on impossible to put on a show that everyone thinks is wonderful (especially on a budget). Sure, it would be nice to get Bruce Springsteen or Bon Jovi in, but until the day the Superbowl gets held darn t'lane it's simply not going to happen.
If you don't like it, go to the bar or the bouncy castle or the facepainters or maybe just read your programme instead.
