Alex, I went to that club in 65 and 66. The name "Don Cunningham" sounds so familiar but I still can't quite put it together, There were several real nice clubs that I went to in the same vicinity as the Playboy Club, and if he played there, he probably played some of those clubs as well.
I like his music, and it sounds familiar. During that time I almost never listened to music in my apartment, I was always on the go.
While listening to his music, I can almost see myself at a "Downtown Club" called "The Upstream", which is another club he probably would have played.
I looked him up, and he played "The Dark Side" in Gaslight Square, an area with a lot of entertainment that I frequented;

Alex you always come up with the winners from the past; a past that I have fond memories of.
Thank you.
