Eighteen years into the 21st century and the class system is still alive and well, in the UK. The apex of that class system seems to be as popular as ever and we still have an unelected parliamentary second chamber where our "representatives" get called Baron or Baroness, except for the ones called Bishop. I've always liked to believe that the people in Scotland are more egalitarian, and indeed support for the monarchy is much lower (53%), but an absence of the class system is too much to hope for. The class system creeps into every aspect of people's lives.
How does memory work? I really don't know. It seems logical that you remember the important events in your life: your child's first spoken word, scoring the winning goal, that time I left my car keys in a foreign country. You probably remember these events because you make an effort to do so. Memories will be reinforced by constant re-telling of the events by you or by friends & family. However, even for those important events it is possible for memories to be wrong. Two people can have a shared experience and yet their respective memories of the sequence of events can differ. That can be a heady mix at this time of year, just add the stress brought on by all the preparations and some Christmas spirits and voilà: a barney.
Usually (concert) gigs belong to that form of show business where the core part of the audience pleasure is provided by some musical diversions but the spectacle forms part of the overall package. An exemplar of this approach are Queen concerts which were (and probably still are) musical entertainments of the highest order but defintely set out to be great spectacles too, which they always achieved.
