One more Paris performance arranged by the theatrical producer (10)
I believe the answer is:
impresario
'producer' is the definition.
(I know that impresario is a type of producer)
'one more paris performance' is the wordplay.
'one' becomes 'I' (Roman numeral).
'performance' indicates anagramming the letters.
'more'+'paris'='moreparis'
'moreparis' anagrammed gives 'mpresario'.
'i'+'mpresario'='IMPRESARIO'
'arranged by the theatrical' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for impresario that I've seen before include "Arranger of concerts, etc" , "opera manager" , "Promoter of public entertainments" , "Entertainment manager" , "Sponsor and manager of public entertainments" .)
