Although this page keeps throwing me an ActiveX error about 10 times before relenting and producing the videos, I love this indepth analysis of the Beatles "A Day in the Life."
The man who "blew his mind out in a car, he didn't notice that the light had changed" is often assumed to be Tara Browne, the young Guinness heir (barely 21 when he died, yet he already had two sons, a wife, and a girlfriend). He may well have been who John Lennon was thinking of, but Paul McCartney wasn't on that same mental track.
That's such an odd line in the Wikipedia entry: "He was known to use drugs recreationally." NO! A friend of the Beatles, living in swinging London in the 1960s, USING DRUGS?
It's kind of like saying "He was known to force his chest to move in and out, taking in oxygen" or "He was known to consume food and drink for sustenance."
