French composer right to abandon burlesque (5)
I believe the answer is:
satie
'french composer' is the definition.
(I've seen this before)
'right to abandon burlesque' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to abandon' indicates named letters should be taken away.
'burlesque' becomes 'satire' (I've seen this before).
'satire' with 'r' taken out is 'SATIE'.
(Other definitions for satie that I've seen before include "French composer of the Gymnopedies, d. 1925" , "Erik -, nineteenth to twentieth century French composer" , "posed by yours truly close to stage" , "French avant-garde composer, Erik, d. 1925" , "scorer" .)
