Quick to appreciate those applauding? (4,3,8)
I believe the answer is:
like the clappers
'quick' is the definition.
('like the clappers' means very quickly)
'appreciate those applauding?' is the wordplay.
'appreciate' becomes 'like' (I've seen this in another clue).
'those applauding?' becomes 'theclappers' (people clapping).
'like'+'theclappers'='LIKE THE CLAPPERS'
'to' is the link.
(Other definitions for like the clappers that I've seen before include "appreciate those people giving one a hand" , "enjoy an appreciative audience" , "very fast!" , "Entertainers do this" , "Very quickly" .)
