Sweeney Todd work: musical censored (7)
I believe the answer is:
haircut
'sweeney todd work' is the definition.
I can't tell whether this defines the answer.
'musical censored' is the wordplay.
'musical' becomes 'hair' (c960s musical).
'censored' becomes 'cut' (I can't justify this - if you can you should give a lot more credence to this answer).
'hair'+'cut'='HAIRCUT'
Can you help me to learn more?
(Other definitions for haircut that I've seen before include "Pageboy is one" , "It proved fatal to Samson" , "Bob, perhaps" , "Bob, say" , "Crop possibly" .)
