Most of those 2,000 living off the Beatles are under 40 - too young to have seen or heard the Beatles live. The Beatles somehow seep into our consciousness. People, who would not call themselves Beatles fans pick up the tunes like nursery rhymes, have the lyrics lodged in their minds. I suppose it's parents who do it. They hum along, still remembering their faves.
Children pick it up, then start to want more.
And so it will go on. I'll buy it, as I buy anything about the Beatles. It will be interesting to listen to, in sequence, to hear the Beatles developing, trying to spot the common denominators which got them to Number One. But I wouldn't recommend it to an absolute beginner wanting to know what the Beatles were all about. Much better to buy an original album, such as Revolver or Sergeant Pepper, which was made and created to be listened to as a whole by four artists at the height of their powers.
