I remember watching Boca Juniors play Argentinos Juniors in Argentina - a country that defines football atmosphere!  It was a Boca home game and there seemed to be "chant leaders" who spent the whole game with their back to the pitch exhorting and encouraging fans in the chants.  Perhaps the hardcore YF guys need to go to this level of organisation to get the results desired.  There was also a fat bastard smoking a big fat cigar for a fair chunk of the game, and I had to sit next to a Liverpool fan - so it wasn't all good....
