Jazz singers used the scat technique, that means using the voice to create notes that are not words so the voice works like a musical instrument - and they also used slang in their music. Vocalists such as Slim Gaillard, and Babs Gonzalez were larger than life characters who used strange, funny new words in rhythmically complex phrases.
Born Lee Brown, 27 Oct. 1919, in Newark NJ; he and his brothers were all called Babs. He studied piano at a young age and learned to play drums. He sang in clubs; wore turban in Hollywood late '40s, calling himself Ram Singh; worked as chauffeur for Errol Flynn; called himself Ricardo Gonzales (Mexican rather than 'Negro') so as to get a room in a good hotel.
