Old duets performed and removed (6)
I believe the answer is:
ousted
'removed' is the definition.
(ousting is a kind of removing)
'old duets performed' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'performed' is an anagram indicator.
'duets' anagrammed gives 'usted'.
'o'+'usted'='OUSTED'
'and' is the link.
(Other definitions for ousted that I've seen before include "Put forcibly out of office" , "Put or forced out of office" , "Drove or ejected from office" , "Put or thrust out" , "Driven out" .)
