Dance stage (4)
I believe the answer is:
step
This clue is a double definition.
'dance' is the first definition.
(I've seen this in another clue)
'stage' is the second definition.
(I've seen this in other clues)
(Other definitions for step that I've seen before include "Pace; foothold" , "Pace (taken one at a time?)" , "Set foot down on pest" , "Bit of mashed potato maybe" , "Foot movement" .)
