I'm returning myself to silent performance (4)
I believe the answer is:
mime
'silent performance' is the definition.
(I've seen this before)
'i'm returning myself' is the wordplay.
'returning' says the letters should be written backwards.
'myself' becomes 'me'.
'im' back-to-front is 'mi'.
'mi'+'me'='MIME'
'to' is the link.
(Other definitions for mime that I've seen before include "Act without words, like Marcel Marceau (4)" , "Theatre with no speech" , "Marcel Marceau's art" , "Job progress" , "Imitate as Marcel Marceau does" .)
