I believe the answer is:

'1977 tony winner for best 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 "Sharpshooter Oakley or musical orphan" , "Popular musical about girl orphan" , "Musical heroine" , "Woman" , "- Get your Gun, musical" .)
