Quite early, while enjoying oneself (2,4,4)
I believe the answer is:
in good time
'quite early' is the definition.
'in good time' can be an answer for 'early' (I've seen this before). I'm unsure of the 'quite' bit.
'while enjoying oneself' is the wordplay.
I cannot really see how this works, but
'while' could be 'time' (I've seen this before) and 'time' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for in good time that I've seen before include "Certainly not late" , "Quite early enough" , "Without risk of being late" , "Quickly" , "How the drummer should play" .)
