What about the other games that season? Did they also have a fantastic atmosphere?
The atmosphere at bigger games takes care of itself, but that's not always the case at run of the mill league or cup games.
When the Singing Section was originally introduced in the East Stand, the improvement in atmosphere at games was very noticeable. It was also quite a decent mix of younger and more... well... 'mature' supporters (in age at least). I think that mix was quite good.
