Book variety performances (4)
I believe the answer is:
acts
This could be a double definition.
'book variety' is the first definition.
'acts' can be an answer for 'book' (I've seen this before). I'm not sure about the 'variety' bit.
'performances' is the second definition.
(act is a kind of performance)
(Other definitions for acts that I've seen before include "Theatrical deeds" , "Behaves or plays" , "5th NT book" , "exerts influence" , "Laws passed" .)
