Slightly different - FA Cup 3rd round home to Villa 1977. We lost 1-0 but had 'scored' earlier on and the Kop went mental, people falling everywhere, many including my dad not realising it had been disallowed. I was a kid sat at the front and walking back to the car wondered why my dad was talking about a replay.
Nearly 50 years later I missed Ayew's goal at Hillsborough going for a p**s.
