Captive audience's ceremony for old player (6,5)
I believe the answer is:
inside right
'old player' is the definition.
(old-fashioned term for a type of footballer)
'captive audience's ceremony' is the wordplay.
'captive' becomes 'inside' (inside can mean in prison).
'audience's' indicates a 'sounds like' (homophone) clue (how it sounds to an audience).
'ceremony' becomes 'rite' (rite is a kind of ceremony).
'rite' is a homophone of 'right'.
'inside'+'right'='INSIDE RIGHT'
'for' acts as a link.
(Other definitions for inside right that I've seen before include "Forward" , "Former footballer" .)
