Sax great Getz (4)
I believe the answer is:
stan
'sax great getz' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stan that I've seen before include "guy" , "Laurel and Hardy, . . . . and Ollie" , "Ollie's partner" , "One of the comic duo" , "- Laurel, Hardy's partner" .)
