Not all of these guests proceed without a break (5)
I believe the answer is:
segue
'without a break' is the definition.
I can't judge whether this definition defines the answer.
'not all of these guests proceed' is the wordplay.
'not all of' says the answer is hidden in the clue (I've seen 'not all' mean this).
'SEGUE' is hidden in the letters of 'these guests proceed'.
Can you help me to learn more?
(Other definitions for segue that I've seen before include "Move between songs, etc, without a pause" , "Play on" , "Move seamlessly from one section to another" , "In music, an immediate transition from one part to another" , "Keep going without interruption" .)
