Whingers affected composer (8)
I believe the answer is:
gershwin
'composer' is the definition.
(George Gershwin, 1898-1937)
'whingers affected' is the wordplay.
'affected' indicates an anagram.
'whingers' with letters rearranged gives 'GERSHWIN'.
(Other definitions for gershwin that I've seen before include "American composer" , "Ira and George, US brother composers" , "Ira -; US lyricist" , "George and Ira ..., American musical brothers" , "Composer of Rhapsody in Blue, d.1937" .)
