Pay attention or bend over (4)
I believe the answer is:
list
I believe this clue is a double definition.
'pay attention' is the first definition.
(I've seen this before)
'bend over' is the second definition.
(I've seen this before)
'or' is the link.
(Other definitions for list that I've seen before include "border" , "Tabulate" , "Ordered array of items" , "Roll; (of ship) lean over" , "band > record" .)
