This BBC article suggests there is some connection between the sets of fans that were there but guess it would only be natural.

i notice they don’t do the remembrance service at Anfield anymore so maybe some have moved on ?
It’s never going to be forgotten by Liverpool and the football world really.
Do they need a memorial at Forest after all these years - maybe not but if fans have asked for once they might consider it ?
