Opera with elephants (4)
I believe the answer is:
aida
'opera with elephants' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aida that I've seen before include "Covent Garden production?" , "title role" , "work of grand proportions" , "She dies with Radams (Verdi)" , "Princess" .)
