Taco Bell was only 6 years old when this radio spot was broadcast on the airwaves. The company had a phenomenal growth spurt in those early years, but it was nothing compared to what would happen to them in the future. By 1967 they had 100 locations and as we know, that was just the tip of the iceberg.
I did not get to experience the Bell for many decades after this commercial, so I was surprised when I heard them say they served burgers. I looked it up and they did serve a sandwich on a bunch, which I believe they called a Bell Burger. It was more like a spicy sloppy joe from the pics I have seen. I would have liked to have tried one, but maybe they weren’t so good, since they do not make them anymore.
