The star entertainer, best of the bunch? (3,6)
I believe the answer is:
top banana
I believe this clue is a double definition.
'the star entertainer' is the first definition.
(I've seen this before)
'best of the bunch?' is the second definition.
(I've seen this before)
(Other definitions for top banana that I've seen before include "figurehead?" , "Star comedian" , "Big cheese" , "1" , "Most important person in group (informal)" .)
