Some of the differences between strip clubs ("the bastard child of misogyny and commerce") and burlesque ("lap-dancing's older, darker, cleverer sister") are well spelled out in last year's How to be a Woman by British columnist Caitlin Moran (godawful title; funny, opinionated, clever memoir).
As Moran tells it, the performer holds the power in burlesque, and their act is about their personality and humour - about "freaky, late-night, libertine self-expression" with a "campy, tranny, fetish element to it".
"Burlesque artists treat their own sexuality as something fabulous and enjoyable," she writes; they sing, talk, laugh and tell jokes.
In contrast, strip clubs have an "oddly aggressive humourless air," she says.
Strip clubs are for people who wish the performers were holograms on the Star Trek holographic deck; fantasy robots with no feelings of their own. Burlesque - such as Mary Jane O'Reilly's In Flagrante at Toto's last weekend - is for people who want to enjoy a performer's enjoyment.
There are structural reasons for this difference. Strippers have to hustle their patrons directly for money. In contrast, if burlesque performers are professional - and there are many who do it purely for the love of it - they are paid an agreed amount for a performance upfront. They're there to have fun with their audience - who are mostly women. They're there to interact with them as people. Very K Rd.
