The YouTube host of this video complains that Rosita does not use doves in her dance, but other birds, thus misrepresenting herself. But as we can see from this article, that is a mere technicality, since Rosita was quite intimate with doves also.
The only other internet reference I can find about "Bambi the Fire Goddess" seems to date her act as far back as 1965. (This foto is from 1970.) It appears then that she had the problem of scorched vajayjay under control.
