Shaw with a clarinet (5)
I believe the answer is:
artie
'shaw with a clarinet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for artie that I've seen before include "Man" , "-- Shaw, jazz musician" , "- Shaw, US jazz clarinettist and bandleader" , "Shaw, perhaps?" , "Guy" .)
