Me, my tastes and loyalties are different and my football related stories less (ahem) meta.
All I can say is that I was listening to my team's fab fan podcast The Spurs Show hosted by comedian Phil Cornwell (probably best know for this) and sometimes featuring that nice fella who bought my old flat and happened on two bits of HERDy goodness that any football (that's soccer to you, my Murkin friends) fan should be familiar with:
1. What it feels like in the crowd
c.11mins in to the particular podcase, Phil notes:
"there's something about being in the congregation…empowering, singing and chanting"
Being "in the congregation" is a great way to describe the almost religious fervour you feel as terrace footsoldier. Which can be just as scary to those alongside you as to those watching over you…for more on the history of crowds and religious fervour, go read this
2. Songs have no obvious parents
c.20 mins in, Phil muses on how songs emerge from a crowd of fans almost fully formed:
"…do they book a rehearsal space, did they workshop it?"
"At a reserve game, maybe" suggests one participant to much laughter
"[Songs] just suddenly emerge. It's like they've all got together and rehearsed it"
Distributed intelligence but it seems a little bit like magic, doesn't it?
