He pretty much spelled it out for everyone back then! "Fireworks and everything..." makes me think of Independence day, which is today. Don't think it's bamsday..but today is definitely going to be a very different kind of 4th of July for me. And I think that was his intent.
No doubt in my mind that he knew Elvis well. It explains the marriage to LMP and so many other things in the hoax. I also like how he stressed the part about not doing drugs, implying that Elvis and him both had reasons to "leave" the life they were living and/or the drug use was only implied and exaggerated by the media. I still believe that he will return, though. I don't think that he will top it off with a world tour or anything but he will reveal that he's not dead - somehow.
What you have just witnessed could be the end of a particularly terrifying nightmare. It isn’t. It’s the beginning.
