Never disapproving about composer (5)
I believe the answer is:
verdi
'composer' is the definition.
(Italian composer Giuseppe Verdi)
'never disapproving about' is the wordplay.
'about' indicates the answer is hidden within the clue (the clue goes around or about the answer).
'VERDI' is hidden within 'never disapproving'.
(Other definitions for verdi that I've seen before include "Drive around to locate opera composer" , "Composer of opera ''Rigoletto''" , "Emblem of the Knights Hospitallers" , "Drive to meet great composer" , "one put on at La Scala" .)
