Comedian Kevin ____ (4)
I believe the answer is:
hart
'comedian kevin' is the definition.

This is the entire clue.
(Other definitions for hart that I've seen before include "providing material for Richard Rodgers?" , "Richard Rodgers and Lorenz . . . . were famous musical partnership" , "Male red-deer" , "Songwriting partnership, Rodgers and --" , "Mature male deer" .)
