I see what you're both saying, but football songs don't actually have to match up exactly to the songs they are based on. I'd prefer the 'proper' version to be sung, but if it makes it easier for it to catch on as a chant with non-1882ers then it might be better just to repeat the same line over and over. Plus then you don't have different people thinking we're at different points in the song and singing different things over one another.
I WANT IT EXACT OR I'M NOT PLAYING.
