A show of some variety (5)
I believe the answer is:
revue
I believe this clue is a double definition.
'a show' is the first definition.
(I know that revue is a type of variety)
'some variety' is the second definition.
(revue is a kind of variety)
'of' acts as a link.
(Other definitions for revue that I've seen before include "(Of butter) tasting off" , "Form of light entertainment" , "Topical variety show" , "Theatrical show" , "Light theatrical entertainment" .)
