I saw a couple of interesting posts about coincidences concerning Michael Jackson and John Lennon.
The first is on the post Famous Coincidences: Michael Jackson's Will And memorial Service. This tells of a coincidence of dates, as the title suggests, between the date of Michael's will and also his memorial service. Both were dated the 7th of July, though obviously years apart. The link will lead to photos verifying the dates etc.
The second is about John Lennon on 67 Not Out's post titled: John Lennon's Photo Predicts His Death. If you look at the photo concerned you'll see the words 'The Best way To Go' and the initials MDC which, as most John Lennon fans will know refer to Mark David Chapman - the guy who killed John. I think the author was struggling a little to make this story work, but see what you think.
