See a musical’s MC (5)
I believe the answer is:
chair
'mc' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'see a musical's' is the wordplay.
'see' becomes 'C' (the word for the letter, according to Chambers).
'a musical' becomes 'hair' (1960s musical).
'c'+'hair'='CHAIR'
Can you help me to learn more?
(Other definitions for chair that I've seen before include "Presiding officer" , "Single seat" , "Professoriate" , "Seat (of learning?)" , "control meeting" .)
