Musical piece to repeat in revised version (8)
I believe the answer is:
operetta
'musical' is the definition.
(thesaurus)
'piece to repeat in revised version' is the wordplay.
'to repeat' can be anagrammed to 'OPERETTA'.
However, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for operetta that I've seen before include "Singing" , "Sung entertainment" , "The Merry Widow, for example" , "The Mikado or The Gondoliers, say" , "Short amusing opera" .)
