Man, more sad news. Seemed he was constantly touring
and gigging so we were fortunate to have a number of
opportunities to see him live.
I also did see Nash the Slash (mentioned upthread by
RetroActive) once, but somewhat worryingly, I cannot
remember exactly when or where

.
I see by my Rock and Roll calendar that today (July18)
is the day Nico passed away in 1988 after having some
sort of medical incident while riding her bike. I saw her
once circa '79-'80, in NYC at CBGB's. There was a very
small crowd (I think she was playing two shows that
night, and I was at the early performance) so it was
easy to get a spot right up front. I was so captivated
by her that it wasn't until after the first set was over
and the guy next to me got up and went to chat to
Nico that I realized I was sitting beside David Bowie.
This is Nico several years before I saw her:
