Variety show valued vile dancing (10)
I believe the answer is:
vaudeville
'variety show' is the definition.
(vaudeville is a kind of variety show)
'valued vile dancing' is the wordplay.
'dancing' is an anagram indicator.
'valued'+'vile'='valuedvile'
'valuedvile' anagrammed gives 'VAUDEVILLE'.
(Other definitions for vaudeville that I've seen before include "variety show" , "Variety entertainment" , "American music hall" , "theatrical entertainment" , "Musical and comedy entertainment" .)
