There's also a walled memorial garden in Hillsborough Park (Middlewood Rd, Leppings Lane side of ground). Not sure about posting links, but just google it.
I lived in Sheffield at the time, had friends who invited LFC fans into their homes etc and who were greatly affected by it, feeling a sense of guilt that this had happened in their city. No-one had any time for the SYP after the miner's strike.
As Lifetime fan says, there were chants of 'There's only one BR' on the Kop at the City game (after the Dalglish chant) but they probably weren't loud enough to be heard at the other end of the ground.
