You, me and that woman to lead to a seat (5)
I believe the answer is:
usher
'lead to a seat' is the definition.
(I've seen this in another clue)
'you me and that woman' is the wordplay.
'you me' becomes 'us' (I can't explain this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'that woman' becomes 'her' (her refers to a woman).
'us'+'her'='USHER'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for usher that I've seen before include "may be match participant" , "Theatre attendant" , "Doorkeeper; one showing to place" , "Theatre guide" , "falling house" .)
