Everyone's pointing out that the Beatles' Sgt. Pepper is 40 years old this weekend.
Most people seem to begin, "It was 40 years ago today Sgt. Pepper taught the band to play," which is complete bollocks. The record says "it was 20 years ago today Sgt. Pepper taught the band to play," so clearly "it was 60 years ago today Sgt. Pepper taught the band to play."
Anyway, if I have to jump on the bandwagon, I'll give you something relatively useful – the URL to a nice website that tells you who all those people on the cover are – the Oxford Dictionary of National Biography site. It only gives you their names, not why they're famous. This is actually part of my cunning plan. If you look them all up on Wikipedia and find out who they all are, and think about it a bit, then you'll actually become one of the sixties generation in a kind of Sapir-Whorf, viral-memey sort of way. Your brain will reform along new lines. Not that being a sixties generation person is the be-all and end-all of civilization, but let's face it, no one who was there can remember it, so having new recruits is the only way to keep on.
