Crew's long hair cut (3)
I believe the answer is:
man
'crew's' is the definition.
(thesaurus)
'long hair cut' is the wordplay.
'long hair' becomes 'mane' (I've seen this before).
'cut' means to remove the last letter.
'mane' with its last letter taken off is 'MAN'.
(Other definitions for man that I've seen before include "Bloke" , "just one" , "See 24" , "Where people compete to win TT" , "Staff the island" .)
