Revolt of bighead in dance (5)
I believe the answer is:
rebel
'revolt' is the definition.
(I've seen this in another clue)
'bighead in dance' is the wordplay.
'bighead' becomes 'b' (the head letter of 'big').
'in' is an insertion indicator.
'dance' becomes 'reel' (reel is a kind of dance).
'b' put into 'reel' is 'REBEL'.
'of' acts as a link.
(Other definitions for rebel that I've seen before include "Insurgent, renegade" , "Insurrectionist" , "Authority fighter" , "Oppose authority" , "Eg, Cade or Hereward" .)
