you are so wrong about this.
Your North Stand idea will not work. What you have to realise is that a different type of Blue goes into each stand. A lot of this is the inheritance from when we relocated from Maine Road. The West Stand is all the old men from the old main stand sit, for example. The North Stand seems mainly families to me.
the vast majority of our vociferous support sit down at the South Stand end.
However, when their is an opportune moment for singing a song, either both of our signing ends start one up at once, or one of our singing ends and the away fans start together.
Either way, the rest of the ground will mainly just join in with sings being sung, if they are loud enough. They don't do it when two songs are started at once.
The North Stand is pretty much the Family stand. Leave it like that. 3 singing sections would make things worse. I know why you are saying this - because of the rare occasion the North Stand starts a song the rest of the ground sometimes joins in. That's mainly because both of our singing areas hear it at once and both start it independantly.
