I saw this too. My first thoughts are that basically this is what the rest of the animal kingdom does (with a few species exceptions), so it may well be in our latent DNA and therefore not be unexpected that a certain section of the community has regressed back to this basic instinct. Animals also fight each other for territory (drug gangs?), so maybe like the ‘Big Bang’ eventually becoming the ‘Big Crush’, the human race is on a predetermined path of self destruction in relation to what we believe to be normal behaviour. If only I could bale out…

hats off to palace, they were always gonna be louder, and hate to say it but they were impressive ALL bouncing and singing.
