"Tomorrow" musical (5)
I believe the answer is:
annie
'tomorrow musical' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for annie that I've seen before include "Inane (anag) - girl (with a gun?)" , "Popular musical about girl orphan" , "Popular musical about Little Orphan" , "-- Lennox, singer" , "-- Oakley (Wild West)" .)
