Revolutionary dance move? (9)
I believe the answer is:
pirouette
'revolutionary dance move?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pirouette that I've seen before include "Whirl round on one's toes" , "Take turn on foot" , "Spin on one foot" , "Tore up tie (anag) - spin" , "Dancer's twirl" .)
