The only Billy Sharp chant I heard was the fat bstard from Sheffield one following his celebrations of the first goal. Seems something blown all out of proportion to me. Also stewards ejected an oldish looking guy near the end for his racists chants (thankfully). Apart from that it just usuall banter.
Re: I was sat right side at cornerflag second row from front.. and never heard this c 1 fan sung the chant and was soon told to shut up, he was sat about 5 rows behind me. totally out of order and he was told there and then he was out of order.
