Back in 1962, Ueki's song "Sudarabushi" became a smashing hit which led to himself and The Crazy Cats to become very much sought-after performers on TV and in movies. Due to his increasingly busy schedule, Ueki hired Matsuzaki, a young man who came from Hakata to Tokyo, to be his driver and assistant. While following Ueki around, Matsuzaki observed up close how the big stars of that era were passionate about their work where they gave their all and were not afraid to look stupid as comedians and created cool music when they were musicians. However, Ueki himself was having doubts about doing such work which required him to fool around and wondered if there was any value in doing this. At the same time, Matsuzaki was treated very nicely by Ueki's family and even called Ueki "Otousan" as his own father had passed away when he was young. Matsuzaki then aspired to become a performer himself as he worked with his teacher Ueki over the years.
