This is Koko’s celebrated hommage to Marlene (Dietrich of course!).
It is classical, elegant- timeless. 

A vision in blue, Koko perches upon a chair, dancing a seductive pax-des-deux,  drawing the audience into her world.  A slow, sensual siren, she leaves a trail of broken hearts and costume pieces lying at her feet. 
As her blue-feathered fans give way to milk-white skin, she will leave you singing Ms. Dietrich’s refrain- „Ich weiß nicht zu wem ich gehöre“ (I don´t know to whom I belong to). 

Well, for this night, you belong to Koko La Douce.
