More than one arrival on stage delights (9)
I believe the answer is:
entrances
This clue is a double definition.
'more than one arrival on stage' is the first definition.
(as in a stage direction to enter)
'delights' is the second definition.
(I've seen this before)
(Other definitions for entrances that I've seen before include "make appearances on stage" , "Fills with delight" , "Delights" , "Charms" , "Transports" .)
