Regarding the 2 changes in traditions:
I don’t like ringing the ‘Victory Bell’ before the game, but when they showed Archie on the live video feed to the scoreboard nobody was going to voice much disapproval. So at least having him do it was a smart move.
They constantly reminded fans with an energetic guy live on the scoreboard video to be loud whenever Texas had the ball, and that worked well. The student section in the end zone was as good as I’ve ever seen it,
The band playing Hang On Sloopy at the end of the third quarter has been a tradition for about 60 years. I missed that, and I can’t even remember what was going on for those couple of minutes. The band did play the song less than 2 minutes of game time later, right after Tate’s outstanding TD catch. And it was a blast to hear that right after the TD.
