Actually the singing spread right round to the side where I was sitting on occasion and I thought the atmosphere - for Wembley - was quite good.Wembley's great, keep it there.
We've been there long enough now though to know that in order to get a decent racket going, we have to keep singing the same song for longer than 10 seconds and then moaning when everyone isn't joining in. It's not rocket science - just persevere with a simple song like 'Come on you reds' or 'Ooh arr we are Exeter' and it will pick up. Give up after a few seconds and it won't.
I should add that I wasn't there yesterday but have been on the two previous occasions and this annoyed me.
