I had nothing against them until a game a few years back - and when I say 'them' i should really say a couple of them.
They had been singing their own songs, ok, thats fine - but its not going to get everyone singing. We started stand free and a group of their younger lads joined in, the next thing I see is one of the slightly older lads (flare boy from Sigma) was there telling them to sit down and stop singing along with us.
