New York Worlds Fair: Summer 1964

I remember visiting the RCA Exhibit and the how much I hated leaving it. I was 13 and my parents had to threaten me to get me out of there. This singing duo was there along with a guy playing an electronic accordion. Sprite had a brand new commercial running that had the same kind of new, electronic keyboard sounds that were coming our of his instrument. I think there were only 2 TK41s there, but I looked at every inch of both of them. I was fascinated by all of it.
