Composer somewhat cross in interview (7)
I believe the answer is:
rossini
'composer' is the definition.
(I've seen this before)
'somewhat cross in interview' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'ROSSINI' is hidden within 'cross in interview'.
(Other definitions for rossini that I've seen before include "opera producer" , "he scored regularly" , "Great musician" , "Largo al factotum composer" , "Composer of the opera William Tell, d. 1868" .)
