Left during performance, being kicked out (8)
I believe the answer is:
deported
'kicked out' is the definition.
(deporting is a kind of kicking out)
'left during performance' is the wordplay.
'left' becomes 'port' (left side of a ship - opposite of starboard).
'during' is an insertion indicator.
'performance' becomes 'deed' (I've seen this in other clues).
'port' placed into 'deed' is 'DEPORTED'.
'being' acts as a link.
(Other definitions for deported that I've seen before include "despatched overseas" , "sent overseas" , "Expelled from a country" .)
