Toy Show (4)
I believe the answer is:
play
I believe this is a double definition.
'toy' is the first definition.
(I know that toy can be written as play)
'show' is the second definition.
(I know that play is a type of musical performance)
(Other definitions for play that I've seen before include "Perform music" , "Uncle's premises" , "Drama; engage in games" , "Stage work" , "stage production" .)
