You mentioned Josephine Baker, well I am far from being an expert on her, so I went on youtube and came up with this clip.
Rather than being encouraged to 'goof' in this it appears she has been perfectly accepted into white society, but when the beat of the drums started she couldn't wait to return to her roots.
