Singer ____ Martin (4)
I believe the answer is:
dean
'singer martin' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dean that I've seen before include "Torvill's ice dancing partner" , "Cathedral dignitary; head of university department" , "college head" , "Glos. forest; Dixie ---, Everton hero" , "Resident fellow" .)
