'we have to continue' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'somehow hunt's got disrupted' is the wordplay.
'disrupted' indicates anagramming the letters.
'somehow'+'hunts'+'got'='somehowhuntsgot'
'somehowhuntsgot' anagrammed gives 'THE SHOW MUST GO ON'.

'but' acts as a link.

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" .)

I've seen this clue in The Irish Times.
