Old crooner and egghead in a drinking bout? (5)
I believe the answer is:
binge
'a drinking bout?' is the definition.
(I've seen this before)
'old crooner and egghead' is the wordplay.
I cannot quite see how this works, but
'crooner' could be 'bing' (Bing Crosby) and 'bing' is found in the answer.
'egghead' could be 'e' (head letter of 'egg') and 'e' is found within the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for binge that I've seen before include "A heavy drinking session" , "Period of excess" , "Eat greedily" , "Bout of indulgence" , "Drink excessively" .)
