Bizarre posts on this subject. Do Liverpool put the words for 'YNWA' up on a big screen? Of course they don't. If it annoys you that you don't know the words, go and look them up or ask your mates. If you're not fussed, just sit/stand in silence. If you're an 'Albion second-teamer', no one cares...
I agree with him. If Sussex by the Sea is our song, we shouldn't need the lyrics on the screen, it looks tinpot. Anyone who is bothered can go away and learn them.
