Return of actor in epic, or performing ... (13)

Ross

I believe the answer is:

'return' is the definition.
(reciprocation is a kind of return)

'actor in epic or performing' is the wordplay.
'performing' indicates an anagram.
'actor'+'in'+'epic'+'or'='actorinepicor'
'actorinepicor' with letters rearranged gives 'RECIPROCATION'.

'of' is the link.

(Other definitions for reciprocation that I've seen before include "Mutual giving and receiving - cop in race riot (anag)", "returning the same gestures?", "Giving, in return".)

I've seen this clue in The Telegraph.
