I thought in the first half the WSU was actually louder than it had been for Donny, which was awesome. North also sounded very strong but faded away a little.
In fact halfway through the first half WSU was trying to get the North to join in the West stand/North stand chant without much success. Took several attempts and much jeering before they finally sparked back into life. Not sure why that was. Perhaps the wind was knocked out of their sails by the away fans singing the "ultras" song, which I have to admit did make me chuckle.
All in all, a great atmosphere when everyone joined in, and thankfully less of the "stand up if you hate Palace" chant that most people don't seem to enjoy.
From the back of the North I heard neither of the things you mention. Just me, or am I going deaf at 21?
