1920s dance (10)
I believe the answer is:
charleston
'1920s dance' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for charleston that I've seen before include "Lively dance - then carols (anag)" , "Lively 1920s' dance" , "Dance making" , "Nineteen twenties dance" , "US city - 1920s' dance" .)
