Is going to give us a song about drinking (8)
I believe the answer is:
swilling
'drinking' is the definition.
(swilling is a kind of drinking)
'is going to give us a song' is the wordplay.
I cannot really understand how this works, but
'give' could be 'swill' (swilling is a kind of giving) and 'swill' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'about' acts as a link.
Can you help me to learn more?
(Other definitions for swilling that I've seen before include "drinking large amount" , "Drinking greedily" .)
