Composer Copland or TV producer Spelling (5)
I believe the answer is:
aaron
I believe this clue is a double definition.
'composer copland' is the first definition.
(I've seen this in another clue)
'tv producer spelling' is the second definition.
(I've seen this in another clue)
(Other definitions for aaron that I've seen before include "Boy" , "leader's brother" , "Brother of Moses who had blessed rod" , "Elder brother of Moses" , "Bearded fellow" .)
