Following performance, ring corporation dogsbody (8)
I believe the answer is:
factotum
'dogsbody' is the definition.
(I've seen this before)
'following performance ring corporation' is the wordplay.
'following' becomes 'f' (used when citing page numbers etc).
'performance' becomes 'act' (act is a kind of performance**).
'ring' becomes 'o'.
'corporation' becomes 'tum' (I've seen this before).
'f'+'act'+'o'+'tum'='FACTOTUM'
(Other definitions for factotum that I've seen before include "Man Friday" , "Versatile employee" , "Assistant doing all kinds of work" , "junior official" , "Jack of all Trades" .)
