Crooner Orbison (3)
I believe the answer is:
roy
'crooner orbison' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roy that I've seen before include "Rob .... was a famous Scottish bandit" , "- Orbison, US singer" , "Man" , "'... Rogers, old film star cowboy (3)'" , "'Rob ..., ... Rogers (3)'" .)
