Lennon and McCartney stopped writing together because Paul McCartney developed a fixation on John Lennon's hair that freaked John out – it's thought that She's Leaving Home was first called I Want To Stroke John Lennon's Lovely Hair.
And he wasn't the only one with a slightly unnatural obsession for John Lennon's hair – because this week an auction sold John Lennon's hair for $48,000. Not all of John Lennon's hair, you understand – that would be creepy – but just a lock of John Lennon's hair. A lock of John Lennon's hair in a bag that you can occasionally open and sniff, pretending that you and John Lennon are such close friends that he can put his hair in a bag and let you smell it. And that's what the mystery hair-buyer will probably do – either that or blast it into the sun, thereby creating an evil nuclear-powered John Lennon to brutally enslave the world with, like in Superman IV.
