As far as references go, the word "yowsah" (an African-American slang term for the word "yes") was used for the first time by Ben Bernie, a jazz violinist and radio personality. When he became a radio personality, the word became his trademark. Some sources say that he coined the word but this has not been confirmed. During the Great Depression, this word was considered African-American slang. This song helped the word regain popularity.
