Taking people to their seats (8)
I believe the answer is:
ushering
'taking people to their seats' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ushering that I've seen before include "Showing people to their seats" , "Taking people to their seats" , "Showing to a seat" , "putting one in one's place" , "working as escorts" .)
