Barber's poignant adagio band played finally (4)
I believe the answer is:
todd
'barber's' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'poignant adagio band played finally' is the wordplay.
'finally' suggests the final letters.
The final letters of 'poignant adagio band played' are 'TODD'.
Can you help me to learn more?
(Other definitions for todd that I've seen before include "Irish-born British actor and soldier, Richard, d. 2009" , "Sweeney, Fleet Street barber" , "Richard --, was Guy Gibson in The Dam Busters" , "19th-century demon barber of Fleet Street" , "Demon 12 of Fleet Street" .)
