Yeah, I assume it’s the mad scramble part of the Horse that’s particularly problematic when there’s a crowd on the field. It’s not just that they’re playing a song, and there’s certainly no copyright nonsense driving not playing it - the band plays all kinds of songs that are audible on TV with no worries.
I also agree that at some point, especially when it’s approaching midnight, the AA just wants to get everybody out so they can shut down the stadium.
I watched a YouTube stream from KQ where a band member asked him to let people know that it was the AA that told them not to play, and I assume it was a combination of the reasons above.
