At the right time; not late (2,3)
I believe the answer is:
on cue
I believe this clue is a double definition.
'at the right time' is the first definition.
(I've seen this before)
'not late' is the second definition.
(I've seen this in another clue)
(Other definitions for on cue that I've seen before include "at the perfect moment" , "(Appearing) just when required" , "as indicated" , "At the correct moment, like efficient actor" , "At the correct moment, like actor speaking lines" .)
