I remember on the coach back from Huddersfield in 2003 (the first time), someone started a chant of 'he's black, he's black, he plays at full-back, Appo..Appo..'
It never caught on, but whether that was to do with the fact that it referenced Appo's skin colour, or because he spent much of 2003 covering 6 while Lee was injured is another matter
