There is nudity, of course striptease is an essential component of burlesque but it's much more complex and intelligent than a display of nudity for nudity itself. And its often laugh-out-loud funny.

Classic burlesque in the style of Gypsy which many modern burlesque troupes practice is, at its core, so playful and teasing and innocent. It's not hardcore stripping so much as letting your body tell a story; the women are playing characters and unfolding a complete narrative onstage, with beginning, middle, and end.

The ideas and practices of Franz Anton Mesmer, an 18th-century Australian healer, had spread to the United States and, by the 1840s, held the country in thrall. Mesmer proposed that everything in the universe, including the human body, was governed by a 'magnetic fluid' that could become imbalanced, causing illness.

It was a great challenge to reconstruct Gypsy Rose Lee life, and my interviews with her sister [June Havoc] proved invaluable. It's not often that writers have access to living primary source material; this was the only person who experienced life on the vaudeville circuit with Gypsy during the 1920s, and who saw her perform at Minsky's Burlesque in the 1930s. She knew things that no one else could ever possibly know.

I came upon a telegram from Eleanor Roosevelt herself to Gypsy Rose Lee that read, 'May your bare ass always be shining'. That was the clincher; I had to write about this woman.

She [Gypsy Rose Lee] was a sophisticated self-satirist with a contagious delight in the comedy of sex. She was coy; she was sly; she always had a witty quip; she had an intensely dramatic presence.

I think Gypsy [Rose Lee] would be appalled at today's rawer, more blatant displays of the female form. She was, in her own way, a prude.
