My wife and I spent our 5-day honeymoon in NYC and spent virtually every evening at Nick's (also spent some time at Condon's, but Nick's was my favorite). Somewhere, I still have the customized match books with our pictures taken by the cigarette girl, and some other "marketing materials."
Over the years, I saw a lot of the greatest jazz players there, that to this day, 50 years later, I remember vividly. I even copied the Nick's style in some of my earliest arrangements (Remember "Just Hot"?).
