Comes back on with performers (7)
I believe the answer is:
returns
'comes back' is the definition.
('return' can be a synonym of 'come back')
'on with performers' is the wordplay.
'on' becomes 're' (regarding).
'with' says to put letters next to each other.
'performers' becomes 'turns' ('turn' can mean a performer as well as their act).
're'+'turns'='RETURNS'
(Other definitions for returns that I've seen before include "Sends back" , "Tickets possibly available" , "Hands back" , "profit" , "Throws made by cricketers" .)
