Musical about Peron (5)
I believe the answer is:
evita
'musical about peron' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for evita that I've seen before include "Eva Peron" , "Andrew Lloyd Webber musical set in Argentina" , "Famous musical" , "1978 Lloyd Webber musical" , "1996 musical film, starring Madonna" .)
