To perform, raised leg on the table? (5)
I believe the answer is:
gigot
'leg on the table?' is the definition.
'gigot' can be an answer for 'leg' (I have seen 'Leg of lamb' mean 'gigot' so perhaps 'leg' could also mean 'gigot'). I'm not certain of the 'on the table?' bit.
'to perform raised' is the wordplay.
'perform' becomes 'gig' (I can't justify this - if you can you should believe this answer much more).
'raised' is a reversal indicator (going up in a down clue).
'to'+'gig'='togig'
'togig' reversed gives 'GIGOT'.
Can you help me to learn more?
(Other definitions for gigot that I've seen before include "joint of meat" , "Perceive by touch" , "Mutton or lamb leg" , "A bit of mutton" .)
