Not working in musical coming up after short musical drama (11)
I believe the answer is:
inoperative
'not working' is the definition.
(I've seen this before)
'in musical coming up after short musical drama' is the wordplay.
'musical' becomes 'evita' (I've seen this before**).
'coming up' is a reversal indicator.
'after' means one lot of letters go next to another.
'short' means to remove the last letter.
'musical drama' becomes 'opera' (I've seen this before).
'evita' back-to-front is 'ative'.
'opera' with its last letter removed is 'oper'.
'ative' put after 'oper' is 'operative'.
'in'+'operative'='INOPERATIVE'
(Other definitions for inoperative that I've seen before include "It's useless" , "Anna -, Russian poet (Requiem)" , "with no effect" , "Not in working order" .)
