Crowd present (4)
I believe the answer is:
host
This clue is a double definition.
'crowd' is the first definition.
(I've seen this in other clues)
'present' is the second definition.
(I've seen this before)
(Other definitions for host that I've seen before include "put on" , "Entertain" , "Pub landlord" , "large group of people" , "TV presenter; large number" .)
