Some alternative backing for musical (5)
I believe the answer is:
evita
'musical' is the definition.
(Andrew Lloyd Webber musical)
'some alternative backing' is the wordplay.
'EVITA' is hidden back-to-front within the letters.
However, I'm not sure how the hidden word is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for evita that I've seen before include "Eva Peron" , "1996 musical film, starring Madonna" , "Well-known musical" , "1978 Lloyd Webber musical" , "Peron musical" .)
