The kind of people who would go to a Dead show 20 years after Jerry Garcia died (or, let's be realistic, the kind who would g to a Dead show during the last 10-15 years of his life).
People like this are directly responsible for me not realizing that the Grateful Dead were, for a period of time before I was born, a really good band (and quite probably the first DIY punks). I didn't actually get past the fan base until my late 20s.
Not that this isn't terrible, but all the drama and people shouting claiming they were spit on and had their asses grabbed are all plants whose job it is to attract attention to the guys in old makeup while they do their acts.
