Maybe, but far be it for me to be sterortypical, but half these people have less that 4 brain-cells and the other half have theirs on loan from the local retard hospital. I think this says it all They either don't know the lyrics, or just aren't patriotic enough to sing which is rather upsetting considering they're wearing the colours of their country.
TBH I think they should sing, or at least make an effort. They look more foolish for not singing than they would if they did sing.
