Guide that woman behind you and me (5)
I believe the answer is:
usher
'guide' is the definition.
(an usher guides people)
'woman behind you and me' is the wordplay.
'woman' becomes 'her' (her refers to a woman).
'behind' says to put letters next to each other.
'you and me' becomes 'us' (the two of us).
'her' after 'us' is 'USHER'.
'that' acts as a link.
(Other definitions for usher that I've seen before include "Show (in or out); doorkeeper" , "Old teacher" , "Doorkeeper in parliament or 29 down" , "Cinema or wedding attendant" , "Theatre/cinema worker" .)
