Show of diversity? (7)
I believe the answer is:
variety
I believe this clue is a double definition.
'show' is the first definition.
(variety show is a kind of show)
'diversity?' is the second definition.
('variety' can be a synonym of 'diversity')
'of' is the link.
(Other definitions for variety that I've seen before include "Sort, type" , "Diversification" , "Diversity - type (of show)" , "Kind (of entertainment?)" , "Type; stage genre" .)
