Crowd shot all over the place (4)
I believe the answer is:
host
'crowd' is the definition.
(thesaurus)
'shot all over the place' is the wordplay.
'all over the place' indicates an anagram.
'shot' anagrammed gives 'HOST'.
(Other definitions for host that I've seen before include "Landlord; army" , "Compere; multitude" , "Entertainer; army" , "Multitude -- MC" , "Entertain" .)
