Show a good man has little cruelty (5)

I believe the answer is:

revue

I'm a little stuck... Click here to teach me more about this clue!

'show' is the definition.
(revue is a kind of show)

I cannot understand how the remainder of the clue works.

(Other definitions for revue that I've seen before include "Kind of show with sketches and songs" , "Show of sketches, songs, etc" , "Entertainment with sketches, songs etc" , "Evening of songs and sketches" , "Topical variety show" .)

I've seen this clue in the Evening Standard.
