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