"A Little Grouch Music" singer (5)
I believe the answer is:
oscar
'a little grouch music singer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oscar that I've seen before include "heard on the radio after November" , "Statuette awarded by Hollywood Academy" , "Film award; --- Hammerstein" , "Film-prize statuette" , "- - Peterson, pianist" .)
