I was in Grade 10 in 1980.
I remember it was sunny & warm for December (on the 9th of course) when we "heard the news".
My friends & I had to take the afternoon off.
What I remember about that night was, after band rehersal, my drummer lived in uptown Manhattan, I'd go to hang frequently after, and we'd always walk past the Dakota. On the fateful night, we had to listen to a test pressing of our first single, so we were in a different neighborhood. Not sure what the timing would have been in regards to the shooting, but...I get shivers when I think about it....
