Queen hit, Don’t Stop Me Now (3,4,4,2,2)
I believe the answer is:
the show must go on
'queen hit don't' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'stop me now' is the wordplay.
I cannot quite see how this works, but
'stop' could be 'go' (going is a kind of stopping) and 'go' is present in the answer.
'me' could be 'us' ('us' can mean 'me' in some dialects) and 'us' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for the show must go on that I've seen before include "Send in the Clowns" , "trouper's philosophy" .)
