Audibly appraises sketch shows (6)
I believe the answer is:
revues
'shows' is the definition.
(revue is a kind of show)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for revues that I've seen before include "Variety shows" , "Entertainments with sketches and songs" , "Theatrical productions" , "Entertainments including song, dance and comedy" .)
