Jolly Good Fellow
I'm pretty sure swarm has always been north endzone next to the band. What you're describing is the same as it is now. I think the previous poster was mistaken
Man things change a lot. Swarm was north end zone when I was student 06-‘11. Frat blocks were north on other side of band. South was general seating and non frat blocks (though plenty of frats took blocks there). I had to show up at gate opening many times to ensure good seats in the south back then, but bad opponents definitely left room for seating.
