Wow! I went through my memory bank as I was reading this. I also remember Elvis dying. I was a tad older than you at the time. I remember one of my teachers wearing black. For a week! Two "celebrity" deaths that will live with me: Princess Diana and less than a week later, Mother Theresa. The latter for much more personal reasons which I've mentioned here...
I've got one for you...I think...yes...here.
There are so many that had profound impact but Elvis was the first major news story I could remember that had such a visceral effect on me. Thank you for the link! I'll check that out.
