Princess Di is a vague memory, I know I was sitting at the kitchen table my best mates house. If it was a Sunday as many have said, there's a very good chance we had just got back from fishing. If it was late on a Sunday there's an extremely good chance I was drunk and that probably explains why it's a bit vague....
9/11; my GF at the time was night owl and watched it live from the very first breaking news story. She woke me up in the very early hours of the morning and we watched the whole thing.
Michael Jackson; don't care for any of his music and even less for him as a person (or parent). But I remember clearly hearing the news on the car radio while driving to see my brand new baby girls for the second time ever. The person means nothing to me, but the memory of emotions that day are very clear.
